Discussion of Block over Block Friction Quiz for JEE & NEET |
Вставка
- Опубліковано 15 гру 2024
- In JEE & NEET, both exams the topic of friction between block over block problems is very important and it forms the basic understanding of cases of friction in mechanics. In PIM video Ashish Arora sir has explained all the concepts for cases of a block over another block is placed and one of the block is pulled by an external force.
In this video Ashish Sir has analyzed all the quiz discussion questions given for students (listed below) and explained in detail about how to approach solutions to such questions. Basic theory with illustration is explained in the PIM video of block over block friction cases which can be accessed through the link - • Block over Block Frict...
For quick revision of friction for JEE & NEET, students can watch Physics Galaxy revision checklist video available at link - • Friction | Revision Ch...
Detailed understanding of the concept can be covered through the Physics Galaxy Concept videos available through our channel playlist or our website.

Practice Quiz Questions solved and analyzed in this video -
Q1. A 4kg block is placed over 5kg block on a smooth ground. Friction coefficient between 5kg and 4kg is 0.5. A force F is applied horizontallay on 5kg block. Find at what value of F sliding will start between the two blocks ?
Ans [45N]
Q2. A 4kg block is placed over 5kg block on a smooth ground. Friction coefficient between 5kg and 4kg is 0.5. A force F is applied horizontallay on 4kg block. Find at what value of F sliding will start between the two blocks ?
Ans [36N]
Q3. A 5kg block is placed over 10kg block on a smooth ground. Friction coefficient between 5kg and 10kg blocks is 0.2. A force F is applied horizontallay on 5kg block. Find at what value of F sliding will start between the two blocks ?
Ans [15N]
Q4. A 10kg block is placed over 20kg block on a rough ground. Friction coefficient between 20kg and ground is 0.2 and that between the two blocks is 0.1. A force F is applied horizontalay on 10kg block. Find at what value of F sliding will start between 20kg and ground then at which value sliding will start between the two blocks ?
Ans [On ground never start, between the blocks at 10N]
Q5. A 20kg block is placed over 20kg block on a rough ground. Friction coefficient between lower 20kg and ground is 0.1 and that between the two blocks is 0.6. A force F is applied horizontallay on upper 20kg block. Find at what value of F sliding will start between lower block and ground then at which value sliding will start between the two blocks ?
Ans [40N, 280N]

Sir, Do you reccomend pathfinder physics book for jee advanced?
happy diwali sir and pls makePim on heat and wave branch sir pls
Sir may you also make video in which the case of more than 2 blocks is covered. I found them to be difficult.
Sir Please make pim for class 12th chapters
Sir.... should I go with ur full theory course for jee preparation....is it covering whole syllabus
👑⛑👒🎩Hats off to ur dedication sir!!! 🙏🙏🙏🤜
I always wait from 12:15 and the video came.
Thank you sir for this video on Diwali day.
Wishing you and your team a happy and prosperous Diwali.

Nice👍
Sir checklist wala suprise kb aayga 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻😖
Sir ko dekh kar physics mai padhne ke liye *hc/lambda* aa jati hai😝😂
Nhi nhi, p^2/2m aa jati h🤣
MC² bhi
Nice sir
Happy diwali to all.
Thanks, wish you and your family a very happy diwali from the entire PG team.
Can anybody clarify what was the surprise sir was talking about?
Sir aap kahan padate ho kota ya koi online coaching ???
Happy Diwali sir,🎉🎉
Thanks, wish you and your family a very happy diwali from the entire PG team.
@@physicsgalaxyworld thank you very much my favorite team ever... ♥
I am not first
I am not last
But, as soon as I clicked very very fast
Sir, from where we should practice questions for NEET???
Sir i need a complete physics playlist can you provide me ,???? please for neet 2021
Sir question 5 mein Jo f2 hai vo niche vale block ko move karvata hai to phir ham Jo uska opposite f2 hai use kyu count Nahin karte ???
Please solve my confusion🙏🙏
Dono friction action nad reaction hain aur dono kabhi ek body pe nahin lagte
@@physicsgalaxyworld
Oh
I have forgotten it
Thank you so much
Sir how can I strong my presence of mind while problem solving which you discussed in jee advanced strategy video ?
Happy Deepawali Sir☺️
Sir what is the Diwali surprise jo aapne story me bola tha
Happy Diwali
Sir which book to follow for KVPY Physics?
SIR I am in class 10th.What books should i follow for olympiads?
Mtg , sof books
Delip what olympiads are you talking about?? SOF or Homi bhabha olympiads like INPHO INMO INCHO?? If its SOF then its quite obvious use MTG books, if its Homi Bhabha then for prmo and RMO use PATHFinder Junior and senior, for inmo you can try out Arthur engel and PYQs, if you are targeting INPHO then solve PG books, do PATHFINDER and Past papers you are Done, for Chemistry olympiad do any coaching material and clayden for organic chemistry....
@@soumadipsen8097 You seem to be a bengali.Can you suggest me which
FIITJEE centre is better in kolkata-south or north Kolkata centre? thanks for your suggestion for physics Olympiad
@@Dilip077 Bro I m a Bengali but currently living in Chennai, I can tell you about the Chennai centres but no idea about Kolkata centres, sorry bro, happy Dipawali from my side
@@soumadipsen8097 Atleast share your views about FIITJEE.That would be helpful for me.
Sir can you please tell the expected dates for jee mains 🙏🙏🙏
Instead of date of exam, we suggest you to focus on your strategies and syllabus completion. Syllabus reduction may not affect much on preparation so we do not suggest to wait for that.
No it's wrong when f=45N then they will move together
where i can get quiz quetions, please upload its pdf in description
In description
Sir isn't there playlist of jee mains geometrical optics 1- i.e. reflection of light???
Yaa i'll upload it of nv sir full lectures ..for now i have gb sir full lectures ..so subscribe it ...
Sir neet me physics me 35+ questions shi krne ke liye kya kre plz sir
Sir mera questions 3rd confusion tha neither mera pura sahi tha
9:58 f (frictional force) should be greater than 40N not the F (applied on upper block)
>>F×0.6=40
>>F=400/6 = 66.7N
Sir after watching your all practice series of blocks and practice from self I says all blocks problem now I will solve 👍👍👍👍🙏🙏🙏🙏 thanks sir..👍👍👍
Happy diwali sir!!!
Thanks for remembering or goal on diwali also!!!
Thanks, wish you and your family a very happy diwali from the entire PG team.
6:12 tarzan incoming lol sir!!!!
😂😂
Sir please tell something about iiit
Please sir please
sir aapne mujhe happy diwali wish nahi kiya😔😔
Aap VIP h kya bhai 😁😁
😮😮😮
Sir waiting for 18th PIM's question discussion because there are no answers in the comments from PG
Jeevan safal ho gya
Thanku sir
Happy Diwali ❤️❤️
I am still studying on Diwali bez I will definitely celebrate my 2021 Diwali in IITD
Too much hard work doesn't required bro for iit preparation 🙄😁
If you are finding it difficult to complete your revision then the best thing you can do is get the ETOOSINDIA short term revision course
