The change in the value of 'g' at a height 'h' above the surface of the earth is the same as at a depth 'd' below the surface of earth. When both 'd' and 'h' are much smaller then the radius of earth, then which one of the following is correct?

Explanation

As per question,
`g' = g(1 - (2h)/(R )) = g (1 - (x)/(R ))`, so, `x = 2h`.
