Jupiter's innermost Galilean satellite, Io is covered with active volcanoes which exist because of the immense gravitational tugging on the satellite by Jupiter and the other moons near Io. Io orbits 4.2 * 10 ^ 1 m from the center of Jupiter. The other satellites have the following orbits Europa 6.7 * 10 ^ 1 m, Ganymede: 10 * 10^9m, and Callisto 1.9 * 10 ^ 9 * m If Jupiter and its satellites are lined up as shown, what is the net gravitational force that Io experiences? ( m = 8.9 * 10 ^ 22 * kg, mg = 4.9 * 10 ^ 22 * kg, mG- 1.5 * 10 ^ 24 * kg, mc = 1.1 * 10^23kg, mJ = 1.9 * 10 ^ 27 lg) You can look up the relative positions of the Jovian moons online if you need.
