2) Three point charges are on the x-axis as shown. The middle charge +Q/2 is a distance d from a-2Q charge on the left, and a distance 2d from a +2Q charge on the right. What is the net electric force on the +Q/2 middle charge? (As usual, a force to the right is positive and a force to the left is negative.) 3) If I have two charges but I am free to choose the charges and magnitude of either of them. In what situation can there be a charge between them which feels zero force?
