Charge of uniform density (20 nC/m2) is distributed over a cylindrical surface (radius = 1.0 cm), and a second coaxial surface (radius = 3.0 cm) carries a uniform charge density of -12 nC/m2 . Determine the magnitude of the electric field at a point 4.0 cm from the symmetry axis of the two surfaces.
 a. 0.45 kN/C
  b. 1.0 kN/C
  c. 0.73 kN/C
  d. 0.56 kN/C
  e. 2.3 kN/C
