Question

Two points charges 20 micocouloumb and -4micocouloumb are separated by a distance of 50 cm in air
1. The point of line joining the charges where the electrostatic potential is zero.
2. The electrostatic potential energy of the system

Answer 1

Answer:

Two charge particles of charges +4 *C and +9 C

are fixed at A and B separated by a distance 20 cm.

Where should be a third point charge 1 C placed

such that net electrostatic force on third charge

becomes zero?
