Two identical point charges of +2.0 μC+2.0\,\mu\text{C} are fixed at (−0.20 m,0)(−0.20\,\text{m},0) and (+0.20 m,0)(+0.20\,\text{m},0). What is the magnitude of the net electric field at the point (0,0.30 m)(0,0.30\,\text{m})? (a) 2.8×105 N/C2.8\times10^{5}\,\text{N/C} (b) 2.3×105 N/C2.3\times10^{5}\,\text{N/C} (c) 4.5×105 N/C4.5\times10^{5}\,\text{N/C} (d) 1.2×105 N/C1.2\times10^{5}\,\text{N/C}
