Find the value of .g(i).at a height of 100 km (ii) at height 6400km fr

1.	Find the value of .g(i).at a height of 100 km (ii) at height 6400km from the surface of the earth. (Radius of the earth = 6400km , g on the surface of the earth = 9.8 ms^(-2) .
Answer» Solution :Using `g_(h) = g(1-(2H)/R)` with h = 100km and R = 6400 KM , `g_(g)= 9.494m//s^2` II) using `g_(h)=(g)/(1+h/R)^2` with h R g = ` 2.45 ms^(-2)`
