Assertion (A) : A force when applied on a body changes its mass.
Reason (R) : Force is the cause which changes the size or shape of the body.
- Both A and R are true and R is the correct explanation of A
- Both A and R are true and R is not the correct explanation of A
- Assertion is true but reason is false
- Assertion is false but reason is true
Answer
Assertion is false but reason is true
Explanation
Assertion (A) is false because a force does not change the mass of the body on which it is applied.
Reason (R) is true because force is that cause which changes the state of a body (either the state of rest or the state of motion) or changes the size or shape of the body.
