-0 .â˘DIn the given figure, if Q, and Q, are positive, where could a negative charge be placed so as to have verticallyupward net force on it?(1) A(2) B(3) O(4) D(5) Et o in the como or the horizontal distance from F |

Answer» The figure shows thefield lines.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. As I said, “Up” is a relative direction. Therefore, in any of the above configuration, for some reference frame, the force will act “vertically Up”. |
