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

`(l)/(v)`

B

`sqrt((2l)/(gsintheta))`

C

`sqrt((2l)/(gcostheta))`

D

`(v)/(gsintheta)`

Text Solution

Verified by Experts

The correct Answer is:
A
Given `a=gtantheta`
Acceleration of block relative to wedge is zero.
Velocity of block`=v`
Distance`=l`
Time `T=(l)/(v)`
