2 identical point charges q each are kept 2 metre apart in air. A third point charge Q of unknown magnitude and sign is placed on the line joining the charges such that the system remains in equilibrium find the position and nature of Q

Expert Answer:

If we place a negative or positive charge of nay magnitude in the middle then the system will reach equilibrium. Because force applied by charge q on Q will cancel out each other.
