Question

3. Consider a "line of charge", where the positive charge per unit length is 1 (in C/m) and the line is "infinitely long". a) Draw the line of charge horizontally on the page. Attempt to draw the E field lines around the line of charge. b) Draw a point on the page that is acting as the cross-section of the line of charge exiting the page. Attempt to draw the electric field lines around the line of charge. c) Choose an appropriate Gaussian Surface. Why did you choose this surface? Apply Gauss's Law to the line of charge and determine the magnitude of the electric field at all points away from the line? Express your answer as a function of the distance (r) from the line of charge.

Answer 1

Gaussian Surface. (cylinder) the of curred surface are having electric field, & perpendicular all the points on same magnitude to field lines; flat surfaces are parallel to field lines. (d) : Gauss's law : $.018 > Sê, vd3, + sez. 13? + [email protected].; - » 0+0+ 6.217 = til 27 & 8
