Solve the following question:
Question: The acceleration due to gravity, g, is constant at sea level on the Earth\'s surface. However, the acceleration decreases as an object moves away from the surface due to the increase in distance from the center of the Earth.
Part A: Derive an expression for the acceleration due to gravity at a distance h above the surface of the Earth, gh.
I need help to solve the above question and express the equation in terms of the radius of the Earth RE, g and h.
