1. The problem statement, all variables and given/known data A straight wire of electric charge truncate to length L has a linear charge density of ρ= 8 C/m. Using a computational approach calculate the electric field due to the truncated line at any arbitrary point in space. Consider L = 1 m, assume line lies along y-axis with the two ends at (0,−L / 2) and (0, L / 2) , and use the MATLAB command quiver to provide a vector plot of the electric field in the x-y plane for a range of −1 m < x < 1m and −1 m < y <1m 2. Relevant equations 3. The attempt at a solution I have attempted at this question and got the following equation: E = [ρ/(4∏εr)] [(sin β1 - sin β2) + (cos β1 - cos β2)] - where β is the angle between an arbitrary point and the line. - sine is in the x direction, cosine is in the y direction in an attempt to get a value instead of an equation, i place point P at the corner of the "imaginary box" (since the limit given to me was a 1 by 1 box). β1 = 56.3° β2 = 26.6° the problem is i don't know how am i suppose to continue. worst of all, i don't get what i am suppose to expect from the graph and having no experience in MATLAB, i don't know how to plot it. a sample code (as shown below) was given to me to analysis but when i tried playing around with the codes using my value, but i got a weird looking graph (not even having a single vector) was given to me.
