A rod of length a and of negligible thickness extends from the point x = 0 to x = a. It contains constant linear charge density pL. Find E (magnitude and direction) at the point (x, y) = (a, a). This problem is 2 dimensional and is in the xy plane. Express your answer in terms of a, Pr and k = - 1/4πεο

1. The floor of a rectangular building has an area of 120 square meter. The length of the floor / is 4m bigger than its width, w. Solve for I. Hint: Start with the equation of the area in terms of I. What kind of equation do you get? /= 48.11 X feet ! No, that's not the correct answer.
