Assertion: The familiar equation `mg=R` for a body on a table is true

1.	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.
Answer» Correct Answer - 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.
