1. [1/5 Points] DETAILS A plastic rod 1.4 m long is rubbed all over with wool, and acquires a charge of -6e-08 coulombs. We choose the center of the rod to be the origin of our coordinate system, with the x-axis extending to the right, the 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? l = 175 m PREVIOUS ANSWERS (b) What is the location of the center of piece number 4? X (d) m. MI4 15.1.022. (c) How much charge is on piece number 4? (Remember that the charge is negative.) -6e-8 X coulombs oximating piece 4 as a point charge, what is the electric field at location A due only to N/C 4? F* j zero magnitude (e) To get the net electric field at location A, we would need to calculate E due each of the 8 pieces, and add up these contributions. If we did that, which arrow above would best represent the direction of the net electric field at location A? |---Select--- MY NOTES PRACTICE ANOTHER
