What is the acceleration due to gravity ...

What is the acceleration due to gravity at a height h ( = radius of the earth) from the surface of the earth ? ltbgt `(g=9.8m//s^(2))`

Text Solution

Verified by Experts

The acceleration due to gravity at a height h ( = radius of the earth) from the surface of the earth is `2.45m//s^(2)`.
`["Explanation : g'"=(GM)/((R+h)^(2))=(GM)/(4R^(2))=(g)/(4)=(9.8)/(4)m//s^(2)=2.45m//s^(2)" for "h=R]`
