Problem

Three point charges are arranged in the xy-plane as follows: +5 μC+5\,\mu\text{C} at the origin, −3 μC-3\,\mu\text{C} at (0.30 m,0)(0.30\,\text{m},0), and +2 μC+2\,\mu\text{C} at (0,0.40 m)(0,0.40\,\text{m}). What are the magnitude and direction of the net electric field at the point (0.30 m,0.40 m)(0.30\,\text{m},0.40\,\text{m})? a) 4.4×105 N/C4.4\times10^{5}\,\text{N/C}, directed 46∘46^{\circ} above the +x+x-axis b) 3.1×105 N/C3.1\times10^{5}\,\text{N/C}, directed 5∘5^{\circ} above the +x+x-axis c) 3.1×105 N/C3.1\times10^{5}\,\text{N/C}, directed 5∘5^{\circ} below the +x+x-axis d) 1.1×105 N/C1.1\times10^{5}\,\text{N/C}, directed along the +x+x-axis
