# Force of gravitational attraction

Not what you're looking for?

(A) A satellite revolves around a planet at an altitude equal to the radius of the planet. The force of gravitational interaction between the satellite and the planet is F_0. Then the satellite moves to a different orbit, so that its altitude is tripled. Find the new force of gravitational interaction F_2. Express your answer in terms of F_0.

(B) Two satellites revolve around the Earth. Satellite A has mass m and has an orbit of radius r. Satellite B has mass 6m and an orbit of unknown radius r_b. The forces of gravitational attraction between each satellite and the Earth is the same. Find r_b. Express your answer in terms of r.
