Required information A 35.0-nC charge is placed at the origin and a 57.0hC charge is placed on the titaxis.= 2.20 cm from the origin. What is the electric potential at a point halfway between these two charges? :IV ! Required information A 35.0-nC charge is placed at the origin and a 57.0-nC charge is placed on the +x-axis, 2.20 cm from the origin. What is the electric potential at a point on the +x-axis 3.40 cm from the origin?Required information A 35.0-nC charge is placed at the origin and a 57.0-nC charge is placed on the +x-axis, 2.20 cm from the origin. How much work does it take for an external agent to move a 45.0-nC charge from a point on the +x-axis, 3.40 cm from the origin to a point halfway between the 35.0-nC and 57.0-nC charges
