A block of mass 2kg rests on a rough inclined plane making an angle of `30^@` with the horizontal. The coefficient of static friction between the block and the plane is 0.7. The frictional force on the block is

A

10N

B

`7sqrt(3)N`

C

`10xxsqrt(3)N`

D

7N

Text Solution

Verified by Experts

The correct Answer is:
A
Since the block is at rest, therefore force of friction
`=mgsintheta=2xx10xxsin30^(@)=10N`
