Question

what is mathematical Expression for gravitational energy​

Answer 1

Answer: Expression for Gravitational Potential Energy at Height (h) – Derive ΔU = mgh. When, h<<R, then, R + h = R and g = GM/R2. ⇒ Note: The weight of a body at the centre of the earth is zero due to the fact that the value of g at the centre of the earth is zero.
