NEET Physics Work Done by Forces Assertion Reason Question
Assertion (A): The work done by friction on a body sliding down an inclined plane is always negative.
Reason (R): Friction always acts in the direction opposite to the displacement of the body.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
