(a) At what point along the line between them is the electric field zero? x m away from the 26.0 PC charge (b) What is the electric field halfway between them? (Enter the magnitude.) IX N/C Enter a number. What is the direction of the electric field? There is no direction because the magnitude of the electric field is zero. along the line between the two charges toward the 45.0 PC charge O along the line between the two charges toward the 26.0 PC charge Additional Materials Reading Submit Answer Practice Another Version
