Two blocks A and B of masses m(A) and m(...

Two blocks A and B of masses `m_(A)` and `m_(B)` have velocity v and `2v` respectively at a given instant A horizontal force F acts on the block A There is no friction between ground and block B and coefficient of friction between A and B is `mu` The friction

A

on A supports its motion

B

on B opposes its motion relative to A

C

on B oppose its motion

D

oppose the motion of both

Text Solution

Verified by Experts

The correct Answer is:
a,b,c
Friction on A and B acts a shown in figure

From the figure it is clear that friction on A supports it motion and on B oppose its motion and always oppose relative motion

Find the minimum value of horizontal force (F) required on the block of mass m to keep it at rest on the wall. Given the coefficient of friction between the surfaces is mu .

Three indentical uniform blocks of mass m each and length L are placed on a smooth fixed horizontal surface as shown. There is friction between A and B (Friction cofficient mu ) while there is no friction between A and C. At the instant shown, that is at t=0, the block A has horizontal velocity of magnitude u towards right, whereas speed of B and C is zero. At the instant block A has covered a distance L relative to block B velcity of all blocks are same. The magnitude of total work done by friction on system of three blocks is
