Begin the exam by writing your name on every page. Show your work to present a clear solution to every problem. If you have any questions, or find any errors, please ask about it! A few bits of useful information: qe = -1.602 times 10-19 C me = 9.11 times 10-31 kg k = 8.99 times 109 N m2/C2 G = 6.67 times 10-11 N m2/kg2 A rectangular surface is in the planje formed by the line z = 2y and the x axis. The square has area 204 cm2 so that A = -1.82 times 10-2m2jhat - 9.12 times 10-3m2khat. An electric field is present given by E = (6.5 j + 55.0k)N/C. What is the flux through the square? How many field lines pierce the square? phi E = A E = (-1.82 times 10-2 m2j - 9.12 times 10-3 m2k ) (6.5j + 55 no field liner pierce the square Scratch paper

Explanation / Answer

flux E is defined as the no. of lines passing through given surface area.

no. of lines N = flux * area

                       = (- 1.82 *10^-2 j -9.12*10^-3 k)* 0.0204 m^2

                       = 3.7128*10^-4 j - 1.86*10^-4 k
