The coefficient of friction between block of mass m and `2m` is `mu=2tantheta`. There is no friction between block of mass 2 m and inclined plane. The maximum amplitude of the two block system for which there is no relative motion between both the blocks is

The coefficient of friction between the block A of mass m & block B of mass 2m is mu . There is no friction between block B & the inclined plane. If the system of blocks A & B is released from rest & there is no slipping between A & B then :

Coefficient of friction between block of mass m and fixed wedge is mu = 0.5 . For what value of (m)/(M) frictional force between block of mass m and wedge becomes zero ?

If coefficient of friction between both the block is mu- (1)/(2) . Find friction force acting between both block.

The coefficient of friction between the block A of mass m & block B of mass 2m is mu . There is no friction between A & B is released from rest & there is no slipping between A & B then:

The coefficient of friction between the block A of mass m and the triangular wedge B of mass M is mu . There in no friction between the wedge and the plane if the system (block A+ wedge B) is released so that there is no stiding between A and B find the inclination theta

The coefficient of friction between block A of mass m_(1)=5kg and block B of mass m_(2)=10 kg is mu_(2)=0.5 . There is no friction froce between block B and fixed horizontal surface. A force of 300N acts on block B in horizontal direction and a horizontal force of magnitude F acts on block A as shown , both towards right. Initially there is no relative motion between the blocks. The minimum value of F such that relative motion starts between A and B is :

A block of mass m is kept on an another block of mass M. The coefficient of friction between the blocks varies as mu=(mu_(0)+kx) while friction between lower block and ground is zero. A time varying force F = 10t is applied horizontally on the upper block. Find time t_(0) when relative motion will start between the blocks. (x is relative displacement between the blocks.)

Calculate angle of friction between wedge and block system is at rest M coefficient of friction between wedge and block.

In the arrangement shown in Fig there is no friction between of mass 2m and ground but there is friction between the block of masses m is stationary with respect to block of mass 2m The value of friction between m and 2m is
