Refer to Figure 7.56. Calculate the change in electric energy along two different paths in moving charge q away from charge

Q from A to B along a radial path, then to C along a circle centered on Q, then to D along a radial path. Also calculate the

change in energy in going directly from A to D along a circle centered on Q. Specifically, what are UB − UA, UC − UB, UD

− UC, and their sum? What is UD − UA? Also, calculate the round-trip difference in the electric energy when moving

charge q along the path from A to B to C to D to A.
