Point charges of 20.0 µC and 45.0 μC are placed 0.450 m apart. (a) At what point (in m) along the line between them is the electric field zero? m away from the 20.0 µC charge (b) What (in N/C) is the electric field halfway between them? (Enter the magnitude.) N/C What is the direction of the electric field? along the line between the two charges toward the 20.0 µC charge There is no direction because the magnitude of the electric field is zero. along the line between the two charges toward the 45.0 µC charge
