Question

In the coordinate system shown at right, particle l with charge q1 = q where q = 5.6 μC, is located at coordinates (-a, 0) m, where a=7.4 m



In the coordinate system shown at right, particle l with charge q1 = q where q = 5.6 μC, is located at coordinates (-a, 0) m, where a=7.4 m; particle 2 with charge q2 = 2q is located at coordinates (a, 0); particle 3 with charge q3=q is located at coordinates (0, a)
