Assertion: For a body to be in equilibrium it must satisfy both the conditions stated simultaneously.
Reason: (a) the vector sum of all the external forces acting on the body should vanish.
(b) the vector sum of all the external torque acting on the body should vanish.

View answer and explanation

Correct option: A

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

Option A (If both assertion and reason are true and reason is the correct explanation of assertion) is correct because both conditions (zero net force and zero net torque) must be satisfied for a body to be in complete equilibrium.
