Reason — The centre of gravity of a body is the point about which the algebraic sum of moments of weights of all the particles constituting the body is zero. This is because the center of gravity is chosen in such a way that the torques (moments) due to the weight of the individual particles balance out, resulting in a net torque of zero.
