An electric field is given by E = sign(x) (300 N/C)i where sign(x) = -1 if a <0 and sign(x) = +1 if x> 0. A cylinder of length 20 cm and radius 4.0 cm has its center at the origin and its axis along the x-axis such that one end is at a = +10 cm and the other is at x = -10 cm. What is the net charge inside the cylinder? A. 2.7 x 1011 C B. 2.7 x 10-7 C C. 9.3 x 10 11 C D. 1.3 x 10 9 C
