FULL SCREEN PRINTER VERSION BACK NE A plastic rod 1.8 m long is rubbed all over with wool, and acquires a charge of -9E-8 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 <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 plece. 2 DAWN zero magnitude (a) What is the length of one of these pieces? (b) What is the location of the center of piece number 8? (c) How much charge is on piece number 87 (Remember that the charge is negative.) coulombs due only to piece 87 (d) Approximating piece 8 as a point charge, what is the electric field at location >NIC Wine Inc Inc.

PRINTER VERSION BACK NEXT A strip of invisible tape 0.19 m long by 0.017 m wide is charged uniformly with a total net charge of 7 nC (nano - 1 10 ) and is suspended horizontally, soit les along the x axls, with its center at the origin, as shown in the figure below. Calculate the approximate electric field at location <0, 0.07,0> m (location A) due to the strip of tape. Do this by dividing the strip into three equal sections, as shown in the figure below, and approximating each section as a point charge. (Assume each point charge is located at the center of the section it approximates. Express your answer in vector form.) (a) What is the approximate electric field at A due to plece 1? E = < (b) What is the approximate electric field at A due to piece 27 > N/C E = (c) What is the approximate electric field at A due to piece 3? > N/C E = < (d) What is the approximate net electric field at A? >N/C
Problem 15.26 An electrostatic dust precipitator that is installed in a factory smokestack includes a straight metal wire of length = 0.8 m that is charged approximately uniformly with a total charge Q-0.3 x10-C. A speck of coal dust (which is mostly carbon) is near the wire, far from both ends of the wire; the distance from the wire to the speck is d = 1.2 cm. Carbon has an atomic mass of 12 (6 protons and 6 neutrons in the nucleus). A careful measurement of the polarizability of a carton atom gives the value = 1.96 * 10-40 (C )(N/C). (a) Calculate the initial acceleration of the speck of coal dust, neglecting gravity. Your answer must be expressed in terms of 0.2.d, and as you can use other quantities in your calculations, but your final result must not include them. It is convenient to use the "binomial expansion that you may have learned in calculus, that (1 + )" 1 + ne * 1. Note that n can be negative. (Enter the magnitude. Use the following as necessary: 0.2.d, u, to, and for the mass of a carbon atom. Use the binomial expansion in your answer.) Edit Calculate the initial acceleration of the speck of coal dust, neglecting gravity. Don't put numbers into your calculation until the very end, but then show the numerical calculation that you carry out on your calculator (Enter the magnitude.) (b) if the speck of coal dust were initially four times as far from the charged wire, how much smaller would be the initial acceleration of the speck?
