Please explain the relation between electric potential energy and electric field in detail.
The electric potential energy of a charged particle is directly proportional to the electric field it experiences. This means that as the electric field increases, the potential energy of the particle also increases.
The electric potential energy of a charged particle can be calculated by multiplying its charge (q) by the electric potential (V) at its location. Mathematically, this can be written as U = qV.
The SI unit for electric potential energy is joules (J), which is also the unit for all forms of energy.
The direction of the electric field determines the sign of the electric potential energy. If the electric field and the direction of the particle's motion are in the same direction, then the potential energy is negative. If they are in opposite directions, then the potential energy is positive.
The work done by an electric force is equal to the change in electric potential energy. This means that if a charged particle moves from one point to another in an electric field, the work done by the electric force is equal to the difference in potential energy between the two points.
