Jupiter is 52 au from the sun based upon distance alone what

Jupiter is 5.2 au from the sun. based upon distance alone, what is the gravitational attraction between Jupiter and the sun in units of earth pulls?

Solution

Gravitational attraction goes as distance squared, so based on distance alone,

Earth force= 1 earthmass / 1AU² = 1 earthpull

Jupiter would have = 1/ (5.2²) = 1/27 earth pulls.
