Two identical point charges, q each are kept 2m apart in air . A third point charge Q of unknown magnitude and sign is placed on the line joining the above two charges such that the system remains in equilibrium. Find the position and nature of Q ?
Dear Student,
if we place a negative or positive charge of any magnitude in the middle then the system will reach equilibrium.but in the given question the force applied by the charge q on the third charge Q will cancel out each other as two identical charge q are given.
