Electric Potential Energy Formula
Electric potential energy occurs due to the interaction of two or more charged particles. As the charged particles come close to each other there will be an electrostatic interaction. In the case of two similarly charged particles, the interaction will be to repel (like charges repel). In the case of two oppositely charged particles, the interaction will be to attract (opposites attract).
Eel = electrostatic potential energy
Q1 and Q2 = electrical charges on the two particles
d = the distance between the charges
Electric Potential Energy Formula Questions:
1. What is the electrostatic potential energy of two electrons that are 345 nm away from each other?
Note: nm refers to a nanometer or 10-9 m and the charge of an electron is equal to -1.60 x 10-19C
2. What is the electrostatic potential of two protons that are 10 cm away from each other?
