A block of mass m is placed on a smooth inclined wedge ABC of inclination `theta` as shown in the figure. The wedge is given an acceleration 'a' towards the right. The relation between a and for the block to remain stationary on the wedge is:

A

`a = g cos theta`

B

`a = g/(sin theta)`

C

`a = g/( "cosec"theta)`

D

`a = g tan theta`

Text Solution

Verified by Experts

The correct Answer is:
D
From wedge reference framee
For block to be at rest
`ma cos theta = mg sin theta`
`a = g tan theta`
