Question
Assertion

The acceleration of a body moving up a rough inclined plane when it is pulled up by a force, depends only on its mass.

Reason

Frictional force acts in the direction of the applied force.

A

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Correct option is D)

The force required to move a body up an inclined plane having coefficient of friction is given by:
. So the acceleration of the body will be:
 which is independent of its mass.

in this case friction acts opposite to the applied force.
