In the figure particle 1 of charge q1 = -3.46q and particle 2 of charge q2 = +1.16q are fixed to an x axis. As a multiple of distance L, at what coordinate on the axis is the net electric field of the particles zero?

In the figure the four particles form a square of edge length a = 5.00 cm and have charges q1 = 9.04 nC, q2 = -21.0 nC, 93 = 21.0 nC, and 94 = -9.04 nC. What is the magnitude of the net electric field produced by the particles at the square's center?

The drawing shows a positive point charge q1, a second point charge q2 that may be positive or negative, and a spot labeled P, all on the same straight line. The distance d between the two charges is the same as the distance between q1 and the spot P. With q2 present, the magnitude of the net electric field at P is twice what it is when q1 is present alone. Given that q1 = 0.50 μ C, determine q2.
