1. The problem statement, all variables and given/known data Two satellites of equal mass, S1 and S2, orbit the earth. S1 is orbiting at a distance r from the earth's center at speed v. S2 orbits at a distance 2r from the earth's center at speed (v/squareroot2) . The ratio of the centripetal force on S1 to the centripetal force on S2 is, A. 1/8 B. 1/4 C. 4 D. 8 2. Relevant equations F = mvsqrd/r 3. The attempt at a solution I just couldn't figure this one out at all... its frustrating, i tried playing around with the equation but i kept getting nonsense.
