A point charge 0.4nC is located at (2,3,3). Find the potential differences between (2,3,3) m and (-2,3,3)m due to the charge:
Correct answer: C. 2.7 Volts
- A. 2.5 Volts
- B. 2.6 Volts
- C. 2.7 Volts
- D. 2.8 Volts
Explanation
The potential at the first point (where the charge is located) is infinite. The potential at the second point is V = kq/r, where r is the distance between the points, which is 4 m. Thepotential difference is thus calculated based on this finite potential, resulting in approximately 2.7 V.

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.
