Three charges are placed on a horizontal line. Charges q1 = +7 nC and q2 = -3 nC are fixed in place, with q2 2.0 m to the right of q1. Charge q3=+5 nC is in equilibrium but free to slide on the line (but not off of it.) a. Find the distance between q3 and q1 and whether q3 is to the right or left of q1. b. If q3 can move along the line away from its initial location, is the equilibrium stable or unstable? How did you decide? c. If q3 were were on a vertical line instead, so it could move up and down but not horizontally, would the equilibrium be stable or unstable for that motion? How did you decide? m
