Suppose the charge q2 can be moved left or right along the line connecting the charges q1 and q3. Given that q = +17 µC, find the distance from q1 where q2 experiences a net electrostatic force of zero? (The charges q1 and q3 are separated by a fixed distance of 19 cm.) q1 = +q q2 = -2.0 q q3 = +3.0 find the magnitude in cm and direction.
