Two equal charges are situated on the x axis at 40.0 cm on either side of the origin as shown in the figure below. Location A is on the perpendicular bisector at a distance of 27.0 cm from the origin on the y axis. (Assume that the +x axis is directed to the right and the +y axis is directed up.) 91 XA 92 (a) If q = -3.75 C and q2 = -3.75 C, what is the net electric field due to both charges at location A? Express your answer in vector form. (b) If 91 = 492 (where q2 = -3.75 C), what is the net electric field at location A due to both charges? Express your answer in vector form.
