Unformatted text preview: y-axis extending up, and the z-axis out of the page. In order to calculate the electric field at location A = <0.7, 0, 0> m, we divide the rod into 8 pieces, and approximate each piece as a point charge located at the center of the piece. (a) What is the length of one of these pieces? 0.1875 [0.188] m (b) What is the location of the center of piece number 7 ? < 0  , -0.46875 [-0.469] , 0  > m. (c) How much charge is on piece number 7 ? (Remember that the charge is negative.) -1.125e-8 [-1.12e-08] coulombs (d) Approximating piece 7 as a point charge, what is the electric field at location A due only to piece 7 ? 7 = < -118.5377 [-119] , -79.3779 [-79.4] , 0  > N/C (e) To get the net electric field at location A , we would need to calculate due each of the 8 pieces, and add up these contributions. If we did that, which arrow would best represent the direction of the net electric field at location A ? g [ g ]...
