Find the value of 'g' at a height 400 km above the surface of earth. Given radius of earth. R= 6400 km and value of 'g' at the surface of earth is `9.8 ms^(-2)`.

Text Solution

Verified by Experts

Value of .g. at a height 400km above the surface is given by= `g. = g ((R )/(R+H))^(2)= 9.8 ((6400)/(6400+ 400))^(2)`
`g.= 8.68 ms^(-2)`
