A body of mass `m` is moved up (slowly) the plane of verying slope by a tangential force upto height `h`. The coefficient of friction between the surface and the block is `mu`.

Select correct option(s)

A

The work done by gravity on the block from `A` to `B` depends upon the height `h`.

B

The work done by gravity on the block from `A` to `B` do not depends upon the height `h`.

C

Total work done by all forces on the block from `A` to `B` is zero

D

From `A` to `B` work done by friction force on the block is negative.

Text Solution

Verified by Experts

The correct Answer is:
