Two positive point charges are placed 2m apart. The electric potential at midpoint due to these two charges will be _:
Correct answer: A. Added to double
- A. Added to double
- B. Reduced to half
- C. Remains same (no effect)
- D. Cancel each other effect
Explanation
Electric potential is a scalar quantity. At the midpoint of two positively charged point charges, the electric potentials of both charges will be added so, the potential is doubled.Solution1m 1m+q--------V=?----------+qV= k q/r + k q/rV=k q/r + k q/rV=2 k q/r.

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.
