Quizplus · Accepted Answer

The center of gravity is the point through which the weight of an object acts and the center of mass is the point where the mass of an object is concentrated. They coincide only when the acceleration due to gravity is constant over the body, which is the case in choice C. In other scenarios, the center of gravity and center of mass may not coincide.
