The field lines for two point charges shown in fig. (i) Is the field uniform? (ii) Determine the ratio qA/qB . (iii) What are the sign of qA and qB ? (iv) Apart from infinity, where is the neutral point? (v) If qA and qB are separated by a distance 10(2–√−1) cm, find the position of neutral point. (vi) where will the lines meet which are coming from A and are not meeting at qB ? (vii) Will a positive charge follow the line of force if free to move?
