Explanation Given: The orbiting radius of the first satellite, r 1 = 7500 km The orbiting radius of the second satellite, r 2 = 15000 km Formula Used: Gravitational force: F = G M m r 2 Where, G is the gravitational constant. M and m are the masses. r is the distance between M and m . Centripetal force : F = m v 2 r Where, m is the mass, v is the velocity and ris the radius. Calculation: F = G M m r 2 = m v 2 r v 2 = G M r v = G M r Where r = R + r 1 for the first satellite and r = R + r 2 for the second satellite
