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.

Options

A. If both assertion and reason are true and reason is a 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 is true and reason are false.

Answer

C

Explanation

For two bodies , the sum of the mutual forces exerted between them is zero from Newton's third law
i.e., `F_(12) + F_(21) = 0`
But the sum of the work done by the two forces need not always concel.
i.e., `W_(12) + W_(21) = 0`
However, it may sometimes be true.
