Two protons are brought towards each other. Will the potential energy of the system decrease or increase? If a proton and an electron be brought nearer, then?

Two protons are brought together. How will potential energy of the system alter?

Two protons are drawn near each other . Will the potential energy of the system increases or decrease ? What will happen if a proton and an electron are drawn near each other ?

If a proton is brought towards another proton, the electrical potential energy of the system

The potential energy when two protons are brought closer and the potential energy ---------------when one proton and one electron are brought close together.

A proton is moving away from an electron, then find the change in potential energy of the system.

In bringing an electron towards another electrons, the electrostatic potential energy of the system
