A very long uniform line of charge has charge per unit length 4.78 μC/m and lies along the x-axis. A second long uniform line of charge has charge per unit length -2.30 μC/m and is parallel to thex-axis at y1 = 0.402 m .

Part A) What is the magnitude of the net electric field at point y2 = 0.182 m on the y-axis?

Part B) What is the magnitude of the net electric field at point y3 = 0.620 m on the y-axis?
