A body of mass `10 kg` lies on a rough inclined plane of inclination `theta = sin^(-1) ((3)/(5))` with the horizontal. When the force of `30 N` is applied on the block parallel to and upward the plane, the total force by the plane on the block is nearly along

A

`OA`

B

`OB`

C

`OC`

D

`OD`

Text Solution

Verified by Experts

The correct Answer is:
A
Friction force along the in upward direction `=10gsintheta-30=30N`
`N=logcostheta=80N`
Direction of `R` is along OA.
