PhysicsEasysingle choice

At a height ' $R$ ' above the earth's surface the gravitational acceleration is ( $R$ = radius of earth, $g$ = acceleration due to gravity on earth's surface)

Options:

Answer:

Solution:

Acceleration due to gravity is given by $g^{'} = \frac{GM}{r ^{2}} = \frac{GM}{( R + h ) ^{2}} = \frac{GM}{( 2 R ) ^{2}} = \frac{GM}{4 R ^{2}} = \frac{g}{4}$
