i. A -15 µC charge is located at (-15, 0) cm, where on the x-axis will a -4.0 µC charge be placed so that the net electric field at the origin is zero? far from point A must a -4.0 µC charge be placed so that the net electric field at A is zero (k = 9 x 109 Nm2 /C2 )? ii. A -20µC charge is placed 25 cm from a 4.0 µC charge. Calculate the magnitude of force between the two charges and state if the force is an attraction or repulsion.
