Electric potential energy is the energy that a charged particle possesses due to its position in an electric field. It is a type of potential energy that is directly related to the electric force between two charged particles.
The electric potential energy between two protons is calculated using the formula U = k(Q1Q2)/r, where k is the Coulomb's constant, Q1 and Q2 are the charges of the protons, and r is the distance between the two protons.
The electric potential energy between two protons is affected by the magnitude of their charges, the distance between them, and the medium in which they are located. It also depends on the direction of the electric field, as it can either add to or subtract from the potential energy.
As the distance between two protons increases, the electric potential energy between them decreases. This is because the electric force between them weakens as the distance increases, resulting in a decrease in the potential energy.
The unit of electric potential energy is joules (J). It is a derived unit that is equivalent to kg*m^2/s^2 or N*m.
