Question

a block of mass m, is kept on a wedge of mass m as shown in figure such that mass m remains stationary w. r. t. The magnitude of force p is

Answer 1

All surfaces are smooth in block of mass m resting on a wedge of mass M remains stationary with m.

The block moves with acceleration with respect to ground.

If a force P is applied to the system as shown in figure such that stationary with respect to block of mass M, then the magnitude of the body could be measured.

Answer 2

Explanation:

acceleration is there where force is

and so this becomes a non inertial frame and concept of pseudo force is used (ma) (refer to diagram in picture)

whose direction is always opposite to the acceleration
