Two positively-charged particles, each having a charge of 3.00 µC, are placed on the x axis. One is at x = 1.00 meter, and the other is at x = -1.00 meter.
(a) Find the electric field on the x axis at x = 0.800 m.
(b) Find the electric field on the y axis at y = 0.800 m.
(c) Find the electric force on a -3.00 µC charge placed on the y axis at y = 0.800 m.
