Some physics lab equipment for manipulating charges is setup for testing. It has an x-y axis visible on it for easy measuring. A +1.00 ?? charge is placed on the y-axis 1.00 centimeters above the origin. A second +1.00 ?? is placed on the y-axis 1.00 centimeters below the origin. What is the electric field at the point (x=1.00 cm, y = 0 cm)?

What is the electric field at the point (x= - 1.00 cm, y = 0 cm)?
