At what altitude above the Earth's surface would the gravitational acceleration be 4.9 m/s^2?(adsbygoogle = window.adsbygoogle || []).push({});

I thought this what very simple but apparently it is not since I got the wrong answer and can't figure out what I did wrong.

I used g= GM/r^2= GM/(R+h)^2 R being radius of earth and h being the altitude.

g= 4.9m/s^2

4.9= (6.73e-11)(5.98e24)/(6.37e6+ h)^2

4.9= 3.99e14-(6.37e6+h)^2

solved for h and got 2.00e7m

Can someone tell me where I went wrong? Thanks
