The value of acceleration due to gravity `(g)` at height `h` above the surface of earth is given by
`g^'=(gR^2)/((R+h)^2)`. If `hlt ltR`, then prove that `g^'=g(1-(2h)/(R))`.

Explanation

To prove that the value of acceleration due to gravity \( g' \) at a height \( h \) above the surface of the Earth is given by

\[ g' = g \left( 1 - \frac{2h}{R} \right) \]

given the formula
