a positively cahrged particle is released from rest in an uniform electric field the electric potential energy of the charge
Hello candidate,
The electric potential energy refers to the energy which is exerted by the charged particle by the virtue of its motion to move against the electric field opposing its direction.
When A positively charged particle is moving in an electric field, it gets attracted towards the negative plate of the electric field and gets repelled by the positive influence of the other plate.
