Compute all parts of given question:
Question: Two 7.00 µC charged particles are located on the x axis. One is at x = 1.00 m, and the other is at x = -1.00 m.
Part A: Determine the electric field on the y axis at y = 0.700 m.
Part B: Calculate the electric force on a -3.00 µC charge placed on the y axis at y = 0.700 m.
Please show your results in detailed calculations.
