Asked by Jane
Two charges are located on the x axis as shown in the figure. d=10.0 cm, q1 =+6.97 μC, and q2 =−10.4 μC. What charge q3 needs to be placed at position x=3d so that the magnitude of the electric field at the origin is zero?

In other words we do not have your figure so we do not really know where the first two charges are located.
