Part (a) of the figure shows two charged particles fixed in place on an x-axis with separation L. The ratio q1/q2 of their charge magnitudes is 4.00. Part (b) of the figure shows the x component Enetx of their electric field along the x-axis just to the right of particle 2. The x-axis scale is set by xs = 32.1cm. (a) At what value of x > 0 us Enetx maximum? (b) If particle 2 has charge -6e, what is the value of that maximum? Assume e = 1.602 x 10-19C.
