    Solution:
    (i) Let C be the point on the line joining the two charges, where electric potential is zero, then

    So, electric potential is zero at distance of 10 cm from charge of 5 × 10-8 C on line joining the two charges between them. If point C is not between the two charges, then

    So, electric potential is also equal to zero a*a distance of 24 cm from charge of -3 × 10-8 C and at a distance of (24 +16) = 40 cm from charge of 5 × 10-8 C, on the side of charge of -3 × 10-8 C.
