The figure shows a horizontal force `vecF` acting on a block of mass M on an inclined plane (angle `theta`). What is the normal reaction N on the block?

`mg sin theta+Fcos theta`

`mg sin theta- Fcos theta`

`mg cos theta-Fsin theta`

`mg cos theta+Fsin theta`

Text Solution

Verified by Experts

The correct Answer is:

From the figure, the normal reaction on the block is `N=mg cos theta+f sin theta`.
