  A) True
  B) False

Question 2

A thin, circular disk of radius 30.0 cm is oriented in the yz-plane with its center at the origin.
 
  The disk carries a total charge of +3.00 C distributed uniformly over its surface. Calculate the magnitude of the electric field due to the disk at the point x = 15.0 cm along the x-axis.
  (0 = 8.85  10-12 C2/N  m2)
  A) 9.95  105 N/C
  B) 4.98  105 N/C
  C) 3.31  105 N/C
  D) 2.49  105 N/C
  E) 1.99  105 N/C
