Question

# Which of the following quantities is zero, when a uniform object is being supported at its center of gravity?

A
Mass
B
Weight
C
Force
D
Moment

Solution

## The correct option is D MomentWhen a uniform object is being supported at its center of gravity, the total weight acts at this point. Hence $$CG =$$ weight due to the presence of weight mass and force of gravity are non-zero. But a moment of force at this point is zero as the object does not turn.Physics
