. Two point charges 'q1' and 'q2' are placed at a distance 'd' apart as shown in the figure. The electric field intensity is zero at a point 'P' on the line joining them as shown. Write two conclusions that you can draw from this.
(i) The two point charges (q1 and q2) should be of opposite nature. Magnitude of charge q1 must be greater than that of charge q2.
