Question

in the usual notation the acceleration due to gravity at height h from the surface of the Earth is.......
a) g = 2 GM : (r + h)
b) g = GM : √r + h
c) g =GM : (R+H)²
d) g = GM(R+H)²
​

Answer 1

Answer:

at height h acceleration due to gravity c)GM/(R+H)^2

Explanation:

if h is very less compared to R then it becomes g times of 1-2h/R
