A smooth wedge of mass M is pushed with ...


A smooth wedge of mass M is pushed with an acceleration `a=gtantheta` and a block of mass m is projected down the slant with a velocity v relative to the wedge.
Q. The time taken by the block to reach the ground is:

A

The time taken by the block to cover distance L on the incline plane is `(L)/(V)`

B

The time taken by the block to cover distance L on the incline plane is `sqrt((2L)/(g sin theta))`

C

The normal reaction between the block and wedge is `mg sec theta`

D

The horizontal force applied on the wedge to produce acceleration a is `(M + m) g tan theta`.
