Sir 59:00 me JEE 2013 question .... Circular platform ka radius is 0.4 and uske ander 2 circular rings ka radius 0.2 .... That means ring ka diameter circular platform ke radius ke equal hai.... But aapne diagram kuch or hi banaya hai and use hi explain kiya hai... 🤔 Please check once if there would be some other condition after correcting the diagram....
Sir 53:00 me JEE 2014 k Question me perpendicular distance of balls when they leave the disc 0.5 nhi hoga?? Kyuki jb balls disc se leave karegi to disc ki boundary pe hogi. Aur circle me centre se boundary k kisi bhi point ka perpendicular distance to radius hi hota h..... Please clear my doubt
Thank you very much sir.

18:30 ..it was asked in my school exam prove dL/dT = tow..i applied same method..my shitty teacher marked that wrong becuase he didnt understand that method..he is just a teacher who follows the school book nothing else
You can ask him to show what is wrong.If he could , agree else say a nice dialogue(Just Kidding, ask him why he didn't give you marks) and walk out in slow motion
Well, as it turns out, in this case the teacher was right. The proof Alakh sir gave us was for symmetrical bodies, and far from rigorous. The full proof goes something like this- *L* = *r* x *p* Differentiating both sides- d *L* /dt=(d *r* /dt x *p* ) + ( *r* x d *p* /dt) {This law comes from vector calculus} The first term in RHS is 0 as velocity is parallel to momentum. Thus d *L* /dt= ( *r* x d *p* /dt)= *r* x *F* which is the result we desired. Here I have boldfaced vectors because arrows were not available. I think Alakh sir knew this already. But teaching this when students are preparing for JEE is quite useless. Humein bas feel agai questions ki 😂😂 Utna bhot hai bhai
Alakh sir se itna achha samjh me aata h ki khin lagta h ki chapter itna kathin aur alakh sir ne itna achha samjhya h iska matlab khin kuch kam padhya h par aisa nhi h alakh sir + self question solving se bhayankar combo kuch bhi nhi h

This is the first time i have solved question of jee advance. I just can't tell you how energetic I'm feeling now... This is i think 7th lesson maybe...and in the 1st attempt i did it . Initially..i was very suffocating inside me reason i was just wondering that I'm just watching it...and nothing else. But the words from alakh sir might have hit me hard..." Try it for 10min and more " you may take 15 if you need. Just do it... I followed it...and the result is stunning. Jee advance question 2014 whose answer is = 4rad/sec ( disc angular velocity)
Sir you are great i am in class 11 and solve jee advance questions correctly by your help solute...to you sir ...meri ek khawaish h ki main aapse milu ....aur I know ye ek na ek din possible jaroor hoga... thanks you sir for this wonderful lecture and I see all your videos and also subscribe your channel... great help sir....👍👍👍👍

45:06 Why the disc will rotate forward if you started running?It should move backward (clockwise) and the disc will try to move Anti clockwise …This video is confusing 45:06
aaj maza aa gaya. Amazing questions sir. Thank you. Tday all question were previous year advanced questions and were from Verma,
Thank you once again
Thanks sir i was facing quite difficulty in this topic you explain every detail in all topics you are a legend.
sir u r real hero.. bcz of u i becomed a successfull person..thnkyu so much
Sir ye sawal humare half yearly examination mee bhi aaya tha............Bohut halwa laga Angular Momentum aapka video dekhkar..........Thank you vey much sir♥♥♥♥♥♥
Did not take care of sign and got wrong answer thanks sir for clearing my misconception in umbrella question
Sir your choice of selection of questions for this topic was awesome
Best ever lecture of angular momentum. thank u sir
1:07:23 Umbrella ☔ problem - answer Platform and boy started rotation with 1.33...... rad/sec opposite direction of omega of umbrella ❤🎉
This is the best lecture of sir
Yehh i finally done adv question thanks a loat sir ji🙏
Thanku sir these videos are equally best for bsc and higher entrance exams. Thanku!

Thank you so much sir for clearing our concepts :)
Sir aapko haste dekh bohot achha lagta haii....❤️
Any 2025 neet aspirant's here... Stilll his vedios are too fresh like a tendercoconut 🎉❤😅
Sir you are the best.Thanks for all your efforts
Sir Neet aspirant ho kr jee advanced ka question jb khud se bnta hai toh next level confidence aata hai❤️💥
Brother 2014-15 ke jee advanced ki cut off bhi 165 thi is saal ki cut off 61 thi levl diffirence dekh
@@exosujunct4932 Bhai pr itna toh hai ki neet ke questions as compared to jee advanced se bohot basic hote hai...toh agar aap hard cheez kr le rhe ho toh basics toh aaram se kr loge
1:17:40 If the star shrinked due to internal explosion...Why the mass of the stars doesn't change ?? Every small particle has their own mass, So it should change and there has a very big change in radius too!!
Why mass will change bro only the shape change na
I am a neet aspirant and doing JEE advanced question just because of Alakh sir ❤❤❤
alakh sir last ke ek minute me bhi ek question kra dete h and baaki utube channels, phle ke 15 min parchar kerte h and last ke 15 min bhi bakwaasbaji me hi nikal dete h
to ase vo humare 30 min barbaad ker dete h, but alakh sir is best jikne liye humari padhai is priority
thankyou so much ALAKH SIR
32:47 what a power sir , such mein kuch gir gaya
1:16:36
The answer for that nebula question is 0.233 seconds, right?
Same answer
6.48×10^-8 hours aayega
Agar convert Kiya to
Yes, same here
Yes bro!,!
2.7 × 10^-6 days 😊
Surely this is one of the best lectures on angular momentum
Mai apne liye bol rha hu ki aapke jaisa koi nhi padha skta koi bhi nhi pata hi nhi chalta kon sa que.hard h 😎
thank you so much alakh sir for this amazing lecture. i could the solve the problem of jee advance and i was so happy!! so much love !!
1:17 when the star shrink the mass changes to Mr³/R³ and remaining all is fine
Mass nehi change hota, volume hota he
Mujhe itni khushi ho rhi h... M NEET wali hu or mne JEE advanced k questions solve kiye sahi answer k sath...
Yay! 😂
Thanks sir for your wonderful lecture ❤❤❤
Your way of teaching and easy explanation has no match. Super awesome.
Jee Advanced ka question solve karne par ek different level ka hapiness or confidence ata he🙂
sir classical mechanics ka degrees of freedom topic example ke sath ek video banaiye.
Sir when do we have to conserve kinetic energy and when do we have to conserve angular momentum how can we identify
We conserve KE in conservative forces and Angular momentum when net ext torque=0
My mind is blast after seeing the question and sir said ye to halwa sabal tha 😭😭😭😭
Bhai kuch samj me nhi aarha hai
Yesab chapter kya karu
it is very IMP first to read the defination of something then watch the concept video ,,, you will know the concepts in ease way
Sir thank you l am now able to solve jee advance question only because of you🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Sir answer is 2k
It's my silly mistake i have forgotten to write 1/4 due to exitement so i will improve myself 🙏🙏
Thanku sir
Right answer is k/2

Sir, answer*
Have u selected in the neet ?
If torque about any axis is zero then angular momentum about that axis is coserverd.
Jst loved the questions of this lacture❤️
I didn't able to solve basic level questions of neet level till before...
After this video, now I am capable to solve advance level questions too😊
Surrrrrrrrrrr...then...sur..sur...sur.. Legend language for physics ❤️❤️❤️❤️❤️❤️😎😎😎
hc Verma answer 42:52=MVR/I+MR^2
sir i really had a very problem in this. thank u for this video. helped me a lot. thank u sir
Sir your lecture is very very amazing
This is the first time i have solved question of jee advance. I just can't tell you how energetic I'm feeling now... This is i think 7th lesson maybe...and in the 1st attempt i did it . Initially..i was very suffocating inside me reason i was just wondering that I'm just watching it...and nothing else. But the words from alakh sir might have hit me hard..." Try it for 10min and more " you may take 15 if you need. Just do it...
I followed it...and the result is stunning.
Jee advance question 2014 whose answer is = 4rad/sec ( disc angular velocity)
Hlwa question tha wo
Bhai answer 8 hai 4 nhi
Sir you are great i am in class 11 and solve jee advance questions correctly by your help solute...to you sir ...meri ek khawaish h ki main aapse milu ....aur I know ye ek na ek din possible jaroor hoga... thanks you sir for this wonderful lecture and I see all your videos and also subscribe your channel... great help sir....👍👍👍👍
