At a depth h1 = R2 from the surface of the earth acceleration due to gravity is g1. It’s value changes by Δg1 when one moves down further by 1 km. At a height h2 above the urface of the earth acceleration due to gravity is g9. It’s value changes by Δg2when one moves up further by 1 km. If Δg1 = Δg2 find h2. Assume the earth to be a uniform sphere of radius R.
