A body on the surface of a planet with the same radius as Earth’s weighs 10 times more than it does on Earth. What is the mass of this planet in terms of Earth’s mass?
Check Your Understanding Earth exerts a tidal force on the Moon. Is it greater than, the same as, or less than that of the Moon on Earth? Be careful in your response, as tidal forces arise from the difference in gravitational forces between one side and the other. Look at the calculations we performed for the tidal force on Earth and consider the values that would change significantly for the Moon. The diameter of the Moon is one-fourth that of Earth. Tidal forces on the Moon are not easy to detect, since there is no liquid on the surface.

The gravitational force FsM that the sun exerts on the moon is per- pendicular to the force FEM that the earth exerts on the moon. The masses are: mass of sun = 1.99 × 10º kg, mass of earth = 5.98 × 10²4 kg, mass of moon = 7.35 × 10² kg. The distances shown in the drawing are rSM = 1.50 x 10" m and reM = 3.85 × 10º m.
