A block mass 'm' is placed on a frictionless inclined plane of inclination `theta` with horizontal. The inclined plane is accelerated horizontally so that the block does not slide down. In this situation vertical force exerted by the inclined plane on the block is:

A

`mg sin theta`

B

`mg cos theta`

C

mg

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
As `a=g tan theta`
`N=Mg cos theta+Ma sin theta`
