Another Gravitation Question

  1. Sep 25, 2008 #1
    The moon Europa, of the planet Jupiter, has an orbital period of 3.55 days and an average distance from the centre of the planet equal to 671,000 Km. If the magnitude of the gravitational acceleration at the surface of Jupiter is 2.36 times greater than that on the surface of the Earth, what is the radius of Jupiter? (hint: begin by calculating the rotation speed.

    So I calculated the velocity and acceleration of the moon, but I am confused on how to calculate the radius with out having the mass of Jupiter, is this where the 2.36 x g comes into play, do I use this to calculate the mass of Jupiter, which will then give me the radius.

    Hint: What force produces the moon's acceleration?
