The correct options are:
<span>1) The force between two charged objects increases as the charge of either one of the objects is increased.
4) The force between two charged objects increases as the objects are placed closer together.
In fact, the electrostatic force is given by Coulomb's law:
</span>
<span>where k is the Coulomb's constant, q1 and q2 are the two charges, r is the separation between the two charges. As we can see from the equation, if one of the charges (q1 or q2) is increased, than the force increases as well (so statement 1) is correct), and if the two objects are placed closer together (r is decreased), the force F increases as well (so statement 4 is correct as well)</span>
