EE 101; Homework 2: Due October 21th Thursday 5PM 1) Four point charges, q 1 = q 2 = q 3 = q 4 =10 µC, are located at (4, 0, 0), (0, 4, 0), (-4, 0, 0) and (0, -4, 0), respectively (in Cartesian coordinate system). Find the total force on the charge q 0 =100 µC which is placed at (0, 0, 4). 2) A line charge of uniform density ρ in free space forms a semicircle of radius R. Determine the magnitude and direction of the electric field intensity at the center of the semicircle. 3) a) An infinitely long cylinder has a circular cross section of radius a . It is filled with charge of constant volume density ρ ch . Find E for all points both inside and outside the cylinder. b) An infinitely long hollow cylinder with an inner radius a and an outer radius b is filled with charge whose volume density in cylindrical coordinates is
