Two charges q1 and q2 are kept on the x-axis, and the electric field at different points on the x-axis is plotted against x. Choose the correct statement about the nature and magnitude of q1 and q2.
From the directions of fields from graph, it is clear that q1 is negative and q2 is positive. Now since electric field is zero to the right of q2, q2 should be smaller in magnitude.
