###### Question details

In the figure, the particles have charges q1 = -q2 = 810 nC and q3 = -q4 = 98 nC, and distance a = 6.8 cm. What are the (a) x and (b) y components of the net electrostatic force on particle 3? The figure shows four particles labeled 1, 2, 3, and 4 plotted in Quadrant 1 on an x y coordinate system. The particles are the vertices of a square with sides of length a. Particle 1 is on the positive y axis, particle 2 is in Quadrant 1, particle 3 is at the origin, and particle 4 is on the positive x axis.
