The correct option is B The total clockwise moment about any reference point is equal to the total anti-clockwise moment about the same point
A body is said to be in complete equilibrium if it is in translational equilibrium as well as rotational equilibrium.
For translational equilibrium, net external force acting on the body must be zero i.e., Fnet=0
i.e no acceleration
For rotational equilibrium, net external torque i.e τnet=0 about a reference point.
Or, total clockwise moment about any reference point is equal to the total anti-clockwise moment about the same point.
Option (A) and (B) must be true.
An object moving with constant angular velocity may have linear acceleration. So option (C) and (D) are wrong.
