Unformatted text preview: A thin plastic rod of length 2.7 m is rubbed all over with wool, and acquires a charge of 67 nC, distributed uniformly over its surface. Calculate the magnitude of the electric field due to the rod a a location 8 cm from the midpoint of the rod. Do the calculation two ways, first using the exact formula for a rod of any length, and second using the approximate formula for a long rod. (a) exact formula E = 5.574e3  N/C (b) approximate formula E = 5.583e3  N/C Extension Request Home My Assignments Page 1 of H 15 HW 2 S2006 5/1/200 ttp://www.webassign.net/v4cgiwcwebb@ncsu/student.pl?n=20060501203157wcwebb@ncsu651652069 PDF created with pdfFactory Pro trial version www.pdffactory.com...
