Question
what is the gravitational field strength of mars measured at a position 400 km above its surface? mars has a mass of 6.39x10^23 kg and a radius of 3390 km.
Correct me if I'm wrong.
G=GM/r^2
G=(6.67×10^-11)(6.39×10^23)/(3390000+400000)^2
G=(6.67×10^-11)(6.39×10^23)/(3790000)^2
G=2.967 m/s^2

looks reasonable but did not do the arithmetic.
