Explanation of Solution
Introduction:
Center of the gravity, also known as center of mass, is the position where the weight of the object is assumed to be concentrated.
Now if the CG of the object is raised, then its height will be changed which will increase the gravitational potential energy since
Conclusion:
Hence, the gravitational potential energy of the object for the considered case will increase.
