At What Height From The Surface Of Earth Is The Value Of G Decreases By 2%?

At What Height From The Surface Of Earth Is The Value Of G Decreases By 2%? Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s− 2 per 3,200 km.) At what
