Two point charges on the x-axis with labeled test positions.
Two point charges on the x-axis with labeled test positions.
Two fixed point charges, each with charge \(+Q\), are located on the \(x\)-axis at \(x = -d\) and \(x = +d\). A small test charge \(+q\) is placed successively at three positions on the \(x\)-axis: Position 1 at \(x = -d/2\), Position 2 at \(x = 0\), and Position 3 at \(x = +d/2\). Which of the following correctly ranks the magnitudes of the net electrostatic forces \(F_1\), \(F_2\), and \(F_3\) exerted on the test charge at Positions 1, 2, and 3, respectively?
