The magnitude of the charges on the rods are: Q1 = 1.46 x 10-17 C and Q2 = 2.20 x 10-17 (This is about the same as the charge of 100 electrons.) The length of the line charges is L= 8.60 x 106m and the distance between the lines is d = 4.27 x 10-6 m. What is the magnitude of the total electric field caused by these two line charges at a point half-way between them and equal distance from the ends of both lines? Give your answer in N/C to at least three significant figures. +Q1
