What is the electric potential energy? Write the relation between the electric potential and the electric potential energy.
Answer :
Definition of electric potential energy : Electric potential energy is defined as the total potential energy a unit charge will possess if located at any point in the outer space.
The electric potential energy of any given charge or system of changes is termed as the total work done by an external agent in bringing the charge or the system of charges from infinity to the present configuration without undergoing any acceleration.
Electric potential energy is a scalar quantity and possesses only magnitude and no direction. It is measured in terms of Joules.
.
Whereas, Electric potential is defined as the total work done by an external agent in bringing the charge or the system of charges from infinity to the present configuration without undergoing any acceleration.
.
Thus : Relation between Electric potential energy and electric potential will be :
U = q V
Where,
U is electric potential energy
q is magnitude of the charge
and, V is electric potential at the given point.
