Assertion: The familiar equation `mg=R` for a body on a table is true only if the body is in equilibrium.
reason: The equality of mg and `R` has no connection with the third law.

A

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

B

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

C

If assertion is ture but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
The two force `mg` and `R` can be different. For example a body in an aeeceleration lift. The equality of `mg` and `R` has no connection with the third law because two force `mg` and `R` can be different.
