  A) parallel to one another and perpendicular to the direction of wave propagation.
  B) parallel to one another and parallel to the direction of wave propagation.
  C) perpendicular to one another and perpendicular to the direction of wave propagation.
  D) perpendicular to one another and parallel to the direction of wave propagation.

Question 2

An LC circuit consists of a 3.4-F capacitor and a coil with a self-inductance 0.080 H and no appreciable resistance. At t = 0 the capacitor has a charge of 5.4 C and the current in the inductor is zero.
 
  (a) How long after t = 0 will the current in the circuit be maximum?
  (b) What will be this maximum current?
  What will be an ideal response?
