Question

The acceleration due to gravity g' at height h from the surface of the earth of radius R is given by g' =gR2/(R+h)2 where g is the acceleration dur to gravity on the earth surface .Find out the value of g' using binomial theorem if h very less than R

Answer 1

Answer:

The gravitational force acting on mass m on the surface of Earth is F = GMmR2 mg = GMmR2 g = GMR2 gR2 = GM ............. (1) where, g is acceleration ...
