Gravitational Force

[LNCO]

1. The problem statement, all variables and given/known data

What would happen if the size of the electrostatic force acting between two positively charged objects was exactly the same as that of the gravitational force acting between them? What would happen if they were moved closer together or further apart?

You probably mean strength of force. In that case, the 2 forces will cancel each other out at that distance between them and they will stay in equilibrium. However, as electrostatic force is much stronger (in term of trillion times or something) than gravitational force, any disturbance would cause them to fly violently apart.
