If the distance between the plates of parallel plates condenser is increased, its potential will
Correct answer: B. increase
- A. will remain same
- B. increase
- C. decrease
- D. decrease exponentially
Explanation
The electric potential is given as V = -E. d. Here E is the electric field and d is the distance between the plates. So, as the distance increases the potential also increases.

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.
