Two charges are placed on the x axis, equidistant from the y axis. The first charge, q1=0.91μC, is placed at the coordinates (d,0), and the second charge, q2=2.32μC, is placed at the coordinates (−d,0) where d=0.448m.

1) There is a location on the x axis, (x0,0), where the net electric field has a magnitude of zero. What is the value, in meters, of x0?
