Two satellites are orbiting a planet at the same height above its surface. The mass of satellite A is m, and the mass of satellite B is 2m. What can you conclude about the planet's gravitational force on the satellites?
(a) The planet's gravitational force on both satellites is the same.
(b) The planet's gravitational force on satellite B is half the gravitational force on satellite A.
(c) The planet's gravitational force on satellite B is twice the gravitational force on satellite A.
(d) The planet's gravitational force on satellite B is four times the gravitational force on satellite A.
