Two positive charges of equal magnitude are fixed in place a distance d apart, as shown in the figure at right. a) Is the electric potential at the midpoint between the charges zero? If so, why? If not, is it positive or negative? Explain your reasoning. b) Say you placed a positive point charge qo at the midpoint. What would be the net electric force on qo? Based on this, describe the motion of qo if it were released from rest. Explain. Say instead that do were released with an initial velocity vo to the right. Determine the velocity of qo when it is very far from the two +Q charges. Show your work and explain your reasoning. Hint: consider the energy of the system of charges.
