Question
(5%) Problem! 11: A 3-D printer lays down a very long straight line of positively charged plastic with a linear charge density of 3.9 uC/m. After the printer has finished a line, the stylus moves a horizontal distancex 2.6 mm to the right as shown. The minute segment of the plastic line highlighted in the diagram has a length dr, and is located r from the stylus tip as shown in the figure Randomized Variables di x-2.6 mm Otheexpertta.com 1196 Part (a) Input an expression for the charge ak on the segment of charge of size dr in terms of given parameters.

a) dq = dr
b) dE= (kdr)/(r^2)
e) E= k(1/x)
f) E= k(1/x) = (9e9)(3.9e-6)(1/(2.6e-3))= 1.35e7
g) Right
