92 at y = 0.2m q1 at x = -0.4m 0,0 The two charges, q, and q2 in the figure above both contribute to the electric potential at the origin (0,0). The net potential at the origin is Vo = 0 V. Given that charge q2 is negative: a.) Is q1 negative or positive? b.) Which charge must have a larger absolute value if Vo = 0, q1 or q2
