Which of the following statements are correct ?
(a)
Centre of mass of a body always coincides with the centre of gravity of the body.
(b)
Centre of mass of a body is the point at which the total gravitational torque on the body is zero.
(c)
A couple on a body produce both translational and rotational motion in a body.
(d)
Mechanical advantage greater than one means that small effort can be used to lift a large load.
