Two satellites of different masses are in the same circular orbit about the eart

Question

Two satellites of different masses are in the same circular orbit about the earth. Which one of the following statements is true concerning the magnitude of the gravitational force that acts on each of them?

(a) The magnitude of the gravitational force is zero newtons for both satellites.

(b) The magnitude of the gravitational force is the same for both satellites, but not zero newtons.

(c) The magnitude of the gravitational force is zero newtons for one, but not for the other.

(d) The magnitude of the gravitational force depends on their masses.

(e) The magnitude of the gravitational force varies from point to point in their orbits.

Explanation / Answer

since the gravitational force is

F=GM1m2/r^2

F = gravitational force of attraction (N)

G=Gravitational Constant

m1,m2 nteracting masses (kg)

r is the separation of the masses (m)

so answer is D

(d) The magnitude of the gravitational force depends on their masses.
