Charge of uniform linear density (4.0 nC/m) is distributed along the entire x axis. Determine the magnitude of the electric field on the y axis at y = 2.5 m.
 a. 36 N/C
  b. 29 N/C
  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
