A block of mass M = 4 kg of height '2b' and breath 'b' is placed on rough plank of same mass M. A light inextensible string is connected to upper end of the block and passed through a light smooth pulley.
Coefficient of friction between block and plank is μ = 0.3.
(A) The maximum value of mass of block A so that block B neither topple nor slide on C
(B) If m = 1 kg then friction between block and plank is 40/9 N
(C) If m = 1 kg then distance of line of action of normal between block and plank and center of block is
(D) Impulse given by force of gravity on the block B is zero in given non-zero time interval.
A rigid massless rod of length L joins two particle each of mass m. The rod lies on a frictionless table. A particle (identical) moving with speed vo collide directly and elastically with one of the particle as shown.
Choose correct options
(A) Angular speed of rod just after collision is
(B) After collision v of the center of the rod is
(C) Velocity of particle just after collision is in backward direction
(D) Magnitude of impulse provided by rod on particle B during collision is
A bead is connected with a fixed disc of radius R by an inextensible massless string in a smooth horizontal plane. If the bead is pushed with a velocity vo perpendicular to the string, the bead moves in a curve and consequently collapses on the disc. Then :
(A) Initial angular acceleration of the particle is
(B) Initial angular acceleration of the particle is
(C) Distance travelled by the particle till it collides with the disc is
(D) Distance travelled by the particle till it collides with the disc is

[@happy333ccc]

Your voice is so clear and easily understanding
Which encouraged me to wa5ch your videos

[@Phyx_IITM]

Thx 🙂

[@KrrishFogat]

Great work bhaiya

[@AYUSHNANDAN-bn9jz]

litreally mind boggling

[@blurryface602]

i think my friend solved this in irodov.
he said it was the most beautiful problem he solved

[@ShivamTank-pq1jz]

Good problem ❌
God problem ✅

[@Phyx_IITM]

😂

[@aryanmathur4610]

Bhaiya please make videos on magnetism and electrostatics

[@ani-sasuke-me_way7.]

Hey!! 1st question came in our narayana advance test

[@dhanya632]

For calculating angular velocity why did you take about particle why not any point on rod

[@nirvastrababa]

Bro takes super conceptual questions and in title be like "GOOD PROBLEMS IN MECHANICS"😭

[@Prabhu108.]

Bhai inki channel ko binge watch karne se would one be prepped for advanced?

[@ArmanKhan-li2hi]

Binge watch krne se to nhi until and unless you try and solve yourself

[@Prabhu108.]

@@ArmanKhan-li2hi abhi se agar koi start kare advanced level prep toh ho sakta hai kya? I have separate notes for interesting questions and the things I learnt from them, but for mains. Should I just start solving advanced questions too?

[@nirvastrababa]

​@@Prabhu108.Yaa bro if you know all the concepts related to the topic then jump right into problem solving...

[@PradipRuj-s7i]

​​@@Prabhu108.Bhai dekh agar problems ko acche se Samajh joage or khud se Kam se Kam 1 hr try karoge to asli benefit milega aur ha ye problems ka main point
Simple Concept nahi balki complex Concept hai jise simple tarike se solve karna hai 😂
BTW these are very good problems only for those who preparing for real jee advanced🗿💀🥶 and olympiads🥶☠️😈
Not meant for jee mains and boards🤡
Sometimes these problems also have difficult and lengthy calculations that I personally don't like

[@kartikeyverma7276]

Bhai aap polar coordinates per vedio lao na

[@anshultiwari2645]

Bhaiya pls take some 12th problems also. Itna mechanics is too much.

[@Beasto.]

Bhaiya plz problems k pdfs bhi

[@CubeRex_]

Why in 1st question we didn't consider gravity and motion of disc

[@aryanbhardwaj_29]

Bcuz the disc is in horizontal plane and the string wraps around it horizontally so there's no change in gpe bcuz there's no change in height.

[@Prince-zz6kt]

Dude "smooth horizontal plane"....and "fixed disc" I guess you missed them out!

[@dipakverma8634]

❤❤❤

[@Bluebowler]

Bhaiya do you take relevant questions?
Like it will be helpful if u do selected ques from irodov

[@Manishyadav20384]

Yes bhaiya please bata do

[@vaibhavshukla2353]

The 1st question is from Irodov only

[@Bluebowler]

@@vaibhavshukla2353 okok

[@ashokpatil7427]

Ns sir ke class problems h🤡

[@Phyx_IITM]

Your point ? These are popular questions u can find on any coachings top material
