Physics 250B Spring 2017 Chapter 22 Homework Exercise 22.17 Enhanced with Solution Exercise 22.17 Enhanced with Solution A very long uniform line of charge has charge per unit length 4 T2 HC/m and lies along the x-axis. A second long uniform line of charge has charge per unit length -2.34 HC/m and is parallel to the x-axis at yh a 0,396 m You may want to review (Da pages 738-742) For related problem solving tips and strategies, you may want to view a Video Tutor Solution of Field of a uniform line charge Submit My Answers Give up Correct The y direction. Part C What is the magnitude of the net electric field at point ys 0.620 m on the yaxis? N/C Submit Answers give incorrect. Try Again; 17 attempts remaining Part D What is the direction of the net electric field at point ys o620 m on the yaxis? My Answers Give UpExplanation / Answer
the net electric filed at point y =0.620 m is
E = lamda1/ 2pi eo y3 - ( - lamda2)/ 2 pi eo ( y3- y1)
=4.72 * 10^-6 / 2pi( 8.85 * 10^-12 ) ( 0.620 ) - ( - 2.34 * 10^-6/ 2pi ( 8.85 * 10^-12) ( 0.620-0.396)
= 3.2 * 10^5 N/C
