The y-component of the electric field of an electromagnetic wave traveling in the +x direction through vacuum obeys the equation Ey = (375 N/C) coskx - (2.20  1014 rad/s)t. (c = 3.0 x 108 m/s)
 
  (a) What is the largest that the x-component of the wave can be?
  (b) What is the largest that the z-component of the wave can be?

Question 2

A cylindrical wire of radius 2.0 mm carries a current of 2.5 A. The potential difference between points on the wire that are 46 m apart is 3.7 V.
 
  (a) What is the electric field in the wire? (b) What is the resistivity of the material of which the wire is made?
