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 negative.
Reason (R): Friction always opposes the direction of motion, resulting in negative work done.
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.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context explains that work done by friction on a body sliding down an inclined plane is negative because the force of friction opposes the motion, leading to negative work.
