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

Question 2

A closed loop conductor that forms a circle with a radius of 2.0 m is located in a uniform but changing magnetic field.
 
  If the maximum emf induced in the loop is 5.0 V, what is the maximum rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?
  A) 0.40 T/s
  B) 2.5 T/s
  C) 0.080 T/s
  D) 5.0 T/s
