A airplane having a metal surface and a wingspan of 25.0 m flies horizontally at 200. m/s where the earth's magnetic field is vertical with magnitude 45.0 T.
 
  (a) What emf is induced across the wings?
  (b) What wingspan would the plane need to produce 1.00-V emf across its wings?
  (c) The plane now reverses direction. Does the polarity of the wingtip emf change? That is, if the left wing was positive before, does it now become negative?

Question 2

The electric field at a point 2.8 cm from a small object points toward the object with a strength of 180,000 N/C. What is the object's charge q? (k = 1/40 = 8.99  109 N  m2/C2 )
 
  A) -16 nC
  B) +16 nC
  C) -17 nC
  D) +17 nC
