Two charges q1 = 4 µC, 92 = -24 µC, are L = 12 cm apart. A third charge is to be placed on the line between the two charges. How far from q, should the third charge be placed so that the net electric force on the third charge is minimized? 4.8 x cm You need to come up with an equation that represents the net force on the third charge as a function of the distance x, then use appropriate calculus to find the value of x where this net force is a minimum.
