The kepler mission has recently discovered a number of rocky planets around the stars.Suppose one of these planets has a mass of 7.66 x 10^24 kg and radius of 6743 km.What is the acceleration due to gravity(that is gravitational field) on the surface of the exoplanet?

Answer 1

g = F/m = G M/r^2
where
G = 6.67*10^-11
M = 7.66*10^24
r = 6.74*10^6

Answer 2

11.2 m/s^2
as compared to 9.81 on earth
