Assertion: Work done by the friction or ...

Assertion: Work done by the friction or viscous force on a moving body in negative.
Reason: Work done is a scalar quantity which cannot be negative like mass.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason are false.

Text Solution

Verified by Experts

Work done is a scalar quantity. It can be positive or negative unlike mass nad kinetic energy which are positive scalar quantities.
