A positive charge, Q>0, is placed at the origin, x=y=0. The points marked with "x" are on the x-axis (A and C) and y- axis (B) with A and B equal distance from the charge Q. The dashed line from A to B is on a circle centered at Q. A) A proton is moved along the dashed curve from point A to point B. The velocity is zero at points A and B. Is the change in the Electric Potential Energy of the system consisting of Q and the proton positive, negative, or zero? Briefly explain your answer. B) A proton is moved from point A to point C along the x-axis. The velocity of the proton is zero at points A and C. Is the change in the Electric Potential Energy of the system positive, negative, or zero? Briefly explain your answer. C.) A student explained their answers to the questions above by saying: The Electric Potential Energy of the proton only depends on how far it is from the charge Q. One way to calculate the change in potential energy is to determine the work done by the electric force as the proton moves closer or further from Q. What is correct about this answer? How can this answer be improved to make it more physically correct or more useful? I
