Assertion : For two bodies , the sum of ...

Assertion : For two bodies , the sum of the mutual forces exerted between them is zero from Newton's third law. Reason : The sum of work done by the two forces must always cancel.

A

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

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
For two bodies, the sum of the mutual forces exerted between them is zero from Newton's third law
`F_12 + F_21=0`
But the sum of the work done by the two forces need no always cancel.
i.e. `W_12 + W_21 =ne0`
However, it may sometimes be true.
