When two bodies collide elastically, then

When two bodies collide elastic, then:

The gravitational force between two bodies is 1 N. If the distance of these two bodies is doubled, what will be the force of attraction between them ?

An amount of charge Q is distributed between two particles. What should be the charges of the two particles so the force of interaction between them is maximum ?

When two bodies of equal masses collide elastically then
