Concerning the gravitational potential energy for the figure C> D. Option D
What is the gravitational potential energy?
The energy that an object has because of its location in a gravitational field—usually one that is close to the surface of the Earth—is known as gravitational potential energy. When an object falls, its potential energy is transformed into kinetic energy, which helps systems impacted by gravity conserve mechanical energy.
Given that the position of C is higher than the position of D and the gravitational potential energy depends on the height of the object thus C>D
