Consider the diagram above. The four dashed lines are electric field equipotential lines. The charge in the middle is a positive point charge. An equipotential line means that along that line, the electric field has the same magnitude. The line closest to the charge (black circle labeled "+") has the strongest field magnitude, and the line furthest from the charge has the weakest field magnitude. A test charge (positive or negative) travels in the space around the point charge. For each travel pathr comment on what happens to the electrical potential energy. A negative test charge travels from C to B U is decreased A A negative test charge travels from F to C U is increased A A positive test charge travels from D to A to B to A to B to A to B to A to B U is unchanged A A positive test charge travels from A to B to E U is increased A A positive test charge travels from A to E U is increased A Check
