Problem

Two point charges, +3 μC+3\,\mu\text{C} and −5 μC-5\,\mu\text{C}, are fixed 0.20 m0.20\,\text{m} apart on the xx-axis. The +3 μC+3\,\mu\text{C} charge is at the origin and the −5 μC-5\,\mu\text{C} charge is at x=+0.20 mx = +0.20\,\text{m}. Which statement best describes the direction of the electric force exerted on the +3 μC+3\,\mu\text{C} charge? (a) There is no net force on the +3 μC+3\,\mu\text{C} charge because the two charges have different magnitudes (b) Toward the +x+x direction, that is, toward the −5 μC-5\,\mu\text{C} charge (c) Toward the −x-x direction, that is, away from the −5 μC-5\,\mu\text{C} charge (d) Along the +y+y direction, perpendicular to the line joining the charges
