user: I'm conducting a physics experiment involving charged particles and electric fields. There's a particle that I've introduced into the field, and it carries a charge of exactly 5 coulombs. The electric field itself has a potential difference of 10 volts. I need to calculate the electrostatic potential energy for this scenario. Can you help me with that calculation?
