Which of Jupiter’s moons has the greatest gravitational force with Jupiter?
2 answers:
Every body in the universe attracts every other body with a force called gravitational force.The gravitational force between two substance are directly proportional to the product of their masses and inversely proportional to the separation distance between them. Mathematically it can be written as -
where m and m' are the masses of two bodies and r is the separation distance between them.
Jupiter is the largest planet in our entire solar system.It has more than 75 moons.Out of all these moons,the four Galilean moons are very large in mass.All others are like simple asteroids.rocks etc whose masses are very small as compared to Galilean moons.These Galilean moons are named as lo,Europa,Ganymede and Callisto.
The lo moon is very close to the Jupiter.The Ganymede moon is the largest moon of the Jupiter which is very big as comparison to mercury also.But it is very far away from Jupiter as compared to lo.
Hence, the force of attraction between Jupiter and lo is very high.It has the greatest gravitational force with Jupiter.
