At what altitude above the Earth's surface would the gravitational acceleration be 4.9 m/s^2?
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
