Two satellites of equal mass,S1andS2, orbit the earth. S1 is orbiting at a distancerfrom the earth's center at speedv. S2 orbits at a distance2rfrom 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.
