Question

If q1 and q2 are positive where could a negative charge be placed so as to have vertically upward net force on it? Pls explain

Answer 1

Answer:

Explanation:

If a negative charge is placed at extreme right or extreme left, the charge will experience a net force in opposite direction. Also, on the line perpendicular to the line joining the charges, the negative charge will experience a net force towards the centre of system.

“Up” is a relative direction. Therefore, in any of the above configuration, for some reference frame, the force will act “vertically Up”.
