Apoint of charge 4.9 μc is placed at the origin (x1 = 0) of a coordinate system, and another charge of -1.1 μc is placed on the x-axis at x2 = 0.28 m. a) where on the x-axis can a third charge be placed in meters so that the net force on it is zero?
b) what if both charges are positive; that is, what if the second charge is 1.9 μc?
