If a particle having a charge q is accelerated through a potential difference V, then the energy acquired by the particle is _.
Correct answer: D. qV
- A. V/2
- B. V/q
- C. qV/2
- D. qV
Explanation
The energy acquired by a particle with charge q when accelerated through a potential difference V is given by the formula:U=qVThis is shown in option D so, option D is the correct choice.

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.
