Explanation:
When a positive charge is shifted from a low-potential region to a high-potential region, the electric potential energy increases.
Definition of Electric Potential Energy:
Electric potential energy is the energy a charged particle possesses due to its position in an electric field.
Electric Potential:
Electric potential is the amount of electric potential energy per unit charge at a given point in an electric field. It is measured in volts (V).
Relationship between Electric Potential Energy and Electric Potential:
The relationship between electric potential energy (U) and electric potential (V) is given by the equation:
U = qV
where U is the electric potential energy, q is the charge, and V is the electric potential.
Explanation:
When a positive charge is moved from a low-potential region to a high-potential region, its electric potential energy increases. This is because the charge experiences an increase in electric potential as it moves to a region with a higher electric potential.
The electric potential energy of a charged particle is directly proportional to the electric potential. So, when the charge is moved to a region with a higher electric potential, its electric potential energy also increases.
This can be understood by considering the analogy of a ball on a hill. When the ball is moved from a lower position on the hill to a higher position, its gravitational potential energy increases. Similarly, when a positive charge is moved from a low-potential region to a high-potential region, its electric potential energy increases.
In summary, when a positive charge is shifted from a low-potential region to a high-potential region, the electric potential energy increases.
