A new planet has been discovered which has a mass of 4.56 x 10^24 kg, and a radius of 7.09 x 10^6 m. What is the gravitational acceleration near the surface of this planet?

Answer 1

G=6.67384 × 10-11 m3 kg-1 s-2
M=4.56*10^24 kg
r=7.09*10^6 m

Using Newton's law of gravitation,
g=Force/1 kg mass
=GM/r² m/s²

Answer 2

5248 m/s^2
