Two points charges, +5µC and -5µC are placed at points A and B, respectively, which are separated by a distance 2d. What is the electric potential at the midpoint M of the line joining A and B?
Correct answer: D. zero
- A. 2kQ/d
- B. kQ/d
- C. -kQ/d
- D. zero
Explanation
The electric potential between the midpoint of two opposite charges with equal magnitudes is always zero.

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.
