A horizontal dashed line represents the x-axis with an origin tick labeled x = 0 at the center, and ticks labeled x = -d and x = +d. Two identical thin ring shapes of radius R are drawn vertically, centered at x = -d and x = +d along the axis. Plus signs are distributed uniformly along the circumference of both rings to indicate positive charge +Q. The axis extends from x = -2d to x = +2d. No other labels, lines, text, or axes appear.
Two positively charged coaxial rings centered at x = -d and x = +d.
Two identical thin rings, each of radius \(R\) and carrying a uniform positive charge \(+Q\), are fixed parallel to each other and centered on a common \(x\)-axis at \(x = -d\) and \(x = +d\), where \(d > R\). Which of the following graphs best represents the electric potential \(V\) along the \(x\)-axis as a function of position \(x\)?
