A ten-loop coil having an area of 0.23 m2 and a very large resistance is in a 0.047-T uniform magnetic field oriented so that the maximum flux goes through the coil. The coil is then rotated so that the flux through it goes to zero in 0.34 s.
 
  What is the magnitude of the average emf induced in the coil during the 0.34 s? A) 0.0032 V
  B) 0.00 V
  C) 0.032 V
  D) 0.32 V
  E) 1.0 V

Question 2

Three equal negative point charges are placed at three of the corners of a square of side d. What is the magnitude of the net electric field at the center of the square? (k = 1/40 = 8.99  109 N  m2/C2)
 
  What will be an ideal response?
