A horizontal axis labeled x extends from left to right. A small filled circle representing a positive point charge sits at position x = 0, labeled +q. To the right, at position x = d, a second small filled circle represents a negative point charge, labeled -Q. Tick marks on the axis indicate the positions x = 0 and x = d. A dashed horizontal line extends along the x-axis to the left of x = 0 into the region x < 0. No other labels, lines, text, or axes appear.
Point charges +q and -Q positioned on the x-axis.
A point charge \(+q\) is fixed at the origin \(x = 0\), and a second point charge \(-Q\) (where \(Q > q > 0\)) is fixed at \(x = d\) on the x-axis. Which of the following expressions represents the position \(x\) on the x-axis at which the net electric field created by the two charges is equal to zero?
