What will be the ratio of acceleration due to gravity on the surface of the earth to the acceleration due to gravity at a height 3 R above the earth's surface? ( R = radius of earth)

Correct answer

16

Step-by-step solution

The value of acceleration due to gravity changes with height ( i e ,   a l t i t u d e ) . If g ′ is the acceleration due to gravity at a point, at height h above the surface of earth, then                                         g ′ = G M R + h 2 b u t ,                             g = G M R 2 ∴       g &#8242
