Two point charges are placed on the x axis. Two charges, labeled q 1 and q 2, are shown on the xy-plane. Point O is at the origin. Charge q 1 lies on the positive x-axis at distance 16 meters from the origin. Charge q 2 lies on the negative x-axis at distance 9 meters from the origin. Points A and B are marked on the positive y-axis at distances 12 meters and 15 meters from the origin, respectively. The first charge, q1 = 8.00 nC , is placed a distance 16.0 m from the origin along the positive x axis; the second charge, q2 = 6.00 nC , is placed a distance 9.00 m from the origin along the negative x axis. Calculate the electric field at point A, located at coordinates (0 m, 12.0 m ).
