Question

calculate the value of accelertion due to the gravity of height R above earth's surface in terms of g where g is acceleration due to at earth's surface and R is the radius of earth.

Answer 1

Explanation:

the value of acceleration due to gravity (g) at height (h) above the surface of the earth is given as

g=gR2/(R+h)²

if h<<r then prove that g¹ =g[2h/r]

g¹=gr²/r+h²

g [r/r+h]²

g [r(1)/r (1+h/r)‐²

binomial expansion =g [1-2h/r]

I think its correct if not then next time I will give my best
