[@kimkong3949]

Dear sir.. I just visited your channel I found your content amazing. Your lecture on rotation Theory were too good. I would be greatful to you if u could upload more videos regarding advanced theory of these topics.

Mast method hai sir.. Conventional method se karne me 1/2hr lag gaya tha.. 👌👌

Very nice. All concepts related to constrained motion got revised.👌

Sir you are amazing.... The way you explained the concepts was fantastic.. 👌

Sir doubt while applying nlm in horizontal direction to get first equation of relation u have considered a2-a1 as net accn for B but it can be opposite also ??Then we get two cases....

[@A2z8747]

Sir, if the conveyor belt is stuck and we put a block on it and run it, then which side will the friction take place? If the accleration is on right side.

[@Raj-ig3wi]

Respected Sir in 1st question acceleration of both the blocks are diff 1st block acceleration is a1 and 2nd block acceleration is a2-a1 Sir won't the string will slag which is not observed in regular problems Sir please clarify my query please 🙏 🙏 🙏

[@PhysicswithAkashGoyal]

the relations obtained in the solutions are correct. whatever you saying is correct when there is no movement of other bodies except blocks. here surface on which the block is kept is also moving. if you observe the situation from bigger block's frame then you will observe the usual behavior

[@Raj-ig3wi]

Ooh, yes sir thanks 🙏🙏

[@Sigma_Bharat_Bhakt]

sir pls tell rules of taking system

[@chaitanyasingla3522]

Kindly make some video on concepts of friction

[@sahayammary8586]

Hi sir, there will be two normal forces on A due to C from both right and left side because it's touching both the gaps and so their sum is zero as they are equal and in opposite direction?

[@PhysicswithAkashGoyal]

If you make free body diagram of A then A is accelerating in Horizontal direction... So there must be net force on it in horizontal... And only horizontal force on it is Normal reaction... So if both normal reactions are acting then these have to be different

[@Physicsdristrophy]

sir how can C move ? is it due to normal force exerted by A sideways

[@eyexo2462]

Naah Bru due reaction force due to pulley on the block b the verticle component get canceled but horizontal position the force remaisn

[@vaibhavkumar5419]

Thank u so much sir

[@vanshikadudeja5871]

How external force(horizontal) could be zero ? As C is moving with acceleration a2 in horizontal direction

[@PhysicswithAkashGoyal]

For which system you are talking about

[@PhysicswithAkashGoyal]

If C is moving with acceleration then Net "external force " on "C" is NOT zero. Here if you see the A+ B+ C system there is No external force along horizontal. If there is any then tell the Name of that force which is external. Tension , Normal whatever Name you take are either internal OR vertical

[@donaldloitam9606]

@@PhysicswithAkashGoyal sir kindly tell which force on c is responsible for its acceleration ..because when i made the free body diagram i could only figure out normal reaction but it was on the opposite direction ..please answer

@@donaldloitam9606 net force on pulley is (sqrt 2) T at 45 degree downward from vertical. its horizontal component will move C towards right

can u please make these in english too

[@Ramesh-ey8fe]

thank you sir

[@enjoywithpj345]

Sir in this question why we are taking acceleration of B to be a2 also. I think a2 will not be there as there is no friction between them so block B will just have acceleration a1 due to tension force in string and it will slip on C with a1 please tell why we are also considering a2 even when there is no friction between B and C

[@cookwiththecook1343]

Hi… a1 acceleration is with respect to the block c so to get the acceleration wrt to ground acceleration a2 is added …yes there will be no friction the a2 added is solely for a1 + a2 (vectors) to be equal to the acceleration in ground frame

[@Ami_S]

Look at the pulley, pulley is getting a force to the right due to tension, who do you think is balancing it, the block C. But teh block C is not fixed so it moves> :>

[@advikatare9087]

How can whole system (A+B+C) can move if there is no ext force in horizontal ?...sir pls resolve my doubt

[@HelloWorld-007]

This is a trick derived from the concept that no Fext is working so summation of all masses acc product is zero

Great sur

Great sir

[@ShahrukhKhan-hg9jj]

[@manpurwarganesh2627]

Sir why c is not moving in 2nd problem?

[@cookwiththecook1343]

Because it is stated in the question . ‘In the figure shown c is a FIXED WEDGE’.
