Jett Roth · Answer 1

The gravitational force between two objects is determined using the formula:

F = (GMm) / r^2, where F is the gravitational force between the two masses, G is the gravitational constant (6.67*10^-11), M and m are the masses of the two objects, and r is the distance between them. Substitute the given values and note that r = 9378 km must first be converted to meters to be consistent with the units. Thus, the gravitational force between Mars and Phobos is 5.16*10^15 N.
