upiter’s moon, Io, revolves around Jupiter in a circular orbit with a radius of 4.22 x 108 m.

(MIo= 8.93 x 1022 kg, MJupiter = 1.9 x 1027 kg, G = 6.67 x 10-11 N m2/kg2)

a. What is the magnitude of the gravitational force on Io from Jupiter?
b. What is the centripetal acceleration of Io?
c. Determine the orbital period, in number of days, of Io’s motion around Jupiter.

can somebody check my answers?
a) 6.35 x 10^22
b) 3.67 x 10^18 m/s^2 <- I don't think this answer is right but I don't know what else it could be.
c) 1.77 days

oops I forgot to put in the ^. It's not 108 it's 10^8, 10^22, 10^27, 10^-11
