2. Two charges, +3q and -q (q is a positive value you don't know), are separated by one meter, as drawn below. a. At which of the labelled positions (every 1/8th of a meter) is the total electric potential zero?Show your work. b. To the right of this position, is the electric potential positive or negative? Explain how you know. c. To the left of this position, is the electric potential positive or negative? Explain how you know. d. What is the electric field at that position (magnitude and direction, if non-zero) if q = 5nC?
