An object with a charge of +7.0 C placed at the origin and an object with a charge of a -3.0 C placed along the x-axis, 25 cm from the origin, at (25 cm, 0). Where, approximately, along the x axis will the electric field be zero, less than 0 cm, between 0 and 25 cm, or greater than 25 cm? Where along the x axis is the electric field zero
