Explanation / Answer

a) Net Horizontal field = 8.98 * 109 * 10-9 * (3 * cos30/0.04322 + 3 * cos30/0.04322 - 2/0.04322)

                                    =   15379.29 N/C

    Net Vertical field = 8.98 * 109 * 10-9 * (3 * sin30/0.04322 - 3 * sin30/0.04322 )

                                    =   0 N/C

Thus, total electric field = (15379.29 i + 0 j) N/C

b)   electric force =   - 4.91 * 10-9 * (15379.29 i + 0 j)

                             =     ( - 7.55 * 10-5 i + 0 j) N
