Electrostatic Potential Energy
Electrostatic potential energy of a system of point charges is defined as the total amount of work done in bringing the different charges to their respective positions from infinitely large mutual separations.
By definition, work done in carrying charge from `oo` to any point is
W = Potential `xx` Charge
This work is stored in the system of two point charges in the form of electrostatic potential energy U of the system.
A positively charged particle is released from rest in an uniform electric field. The electric potential energy of the charge
Options:
(a) remains a constant because the electric field is uniform
(b) increases because the charge moves along the electric field
(c) decreases because the charge moves along the electric field
(d) decreases because the charge moves opposite to the electric field
