a. Show that the electric potential along the axis of the ring is given by V = Ke where r= V(R2 + x2). To get full credit, start with a dq, mark all your variables in the figure, and show the few steps to get to this result. b. A negative point charge q = -5.0 nC is placed at point P, a distance 8.00 cm from the center of the ring along the axis. How much work was required to place the charge q at P? Assume that it is being-brought from infinity. c. Now, if you release the negative chargeq at P from rest, describe the subsequent motion of the charge. d. Where does it have the maximum speed and what is its maximum speed? Take the mass of the charge q to be 5.00 milligrams. Work this out on a piece of paper.
