Three point charges are aligned along the x axis as shown in Figure P15.49. Find the electric field at the position x = +1.9 m, y = 0. Magnitude N/CDirection The field is in the +x direction. The field is in the -x direction. There is no field at the position x = +1.9 m, y = 0. The field is in the -y direction. The field is in the +y direction. -0.50 m- -0.80 m- - 4.0 nC 5.0 nC 3.0 nC Figure P15.49
