The table shows data for four planetary bodies. If your mass is 68.05 kg, how much gravitational force would you experience on the surface of Mercury?
Newton's law of gravitation is F gravity Gm m2. The gravitational constant
Gis 6.67 * 10-11 Nm2/C2 (For the purposes of calculating the gravitational
force between a planet and an object on its surface, the distance ris the
radius of the planet.)
