Q. Illustrate what does gravitational force depend on?
Answer:-
The Gravitational force depends on distance as well as mass. Therefore the formula for calculating gravitational force between 2 objects with a given distance
G [(mass 1) (mass2)]/distance squared.
G is a universal gravitational steady 6.67 x 10 increased to -11 powers. Regretful if it's a little confusing to read since I cannot do basic math operations here.
