The electric field and potential field produced by three-point charges is shown in the figure below. The potential field is color coded with brightness around the charges representing the values. Red indicates a positive potential, while blue indicates negative potential. Brighter the color, larger the value. The green lines are equipotential lines where the potential is same everywhere on the line. A charge of q=2.0μC is moved from point A to point B. (a) Calculate the work done and change in potential energy in moving the charge from A to B. Does the charge speed up or slow down moving from A to B? (b) What is the work done and change in potential energy if the charge has the same magnitude as q but is negative?
