NCERT Exercise 2.1 - Electrostatic Potential and Capacitance
Question: Two charges 5 × 10⁻⁸ C and -3 × 10⁻⁸ C are located 16 cm apart. At what point(s) on the line joining the two charges is the electric potential zero? Take the potential at infinity to be zero.
Answer: Electric potential is zero at **10 cm** from the positive charge (between the charges) and at **40 cm** from the positive charge (on the side of the negative charge).
