Mars has a radius of about 0.38 Earth radius and a mass of only 0.11 Earth mass. Estimate the acceleration due to gravity on Mars.

gmars=.11^2/.38 * 9.8=?
Answered by Chanz
This question is wrong. Mars' GRAVITY is about .38 Earth's. It's radius is about .54 Earth's. So by universal gravitation
g = GM/r^2

g = G .11 / (.54 r)^2 =
.11/.54^2 *9.8
