A positive charge is moved against an electric field. Its P.E will :
Correct answer: A. Increases
- A. Increases
- B. Remains same
- C. Decreases
- D. May increase or decrease depending upon magnitude of charge
Explanation
a) When a positive charge is moved against an electric field, its potential energy increases. b) If a positive charge remains stationary within an electric field, its potential energy remains the same. c) When a positive charge moves in the same direction as the electric field, its potential energy decreases. d) The magnitude of the charge does not determine the change in potential energy; it depends on the direction of movement relative to the electric field .

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
