c. 43 N/C
d. 50 N/C
e. 58 N/C

Question 2

A long cylindrical shell (radius = 2.0 cm) has a charge uniformly distributed on its surface. If the magnitude of the electric field at a point 8.0 cm radially outward from the axis of the shell is 85 N/C, how much charge is distributed on a 2.0-m length of the charged cylindrical surface?
a. 0.38 nC
b. 0.76 nC
c. 0.19 nC
d. 0.57 nC
e. 0.98 nC
