[ap345]

A conducting rectangular loop of mass M, resistance R, and dimensions a  b is allowed to fall from rest through a uniform magnetic field which is perpendicular to the plane of the loop. The loop accelerates until it reaches a terminal speed (before the upper end enters the magnetic field). If a = 2.0 m, B = 6.0 T, R = 40 , and M = 0.60 kg, what is the terminal speed?
 
   

   
  a.
  1.6 m/s
   
  b.
  20 m/s
   
  c.
  2.2 m/s
   
  d.
  26 m/s
   
  e.
  5.3 m/s

Question 2

The coil shown in the figure has 2 turns, a cross-sectional area of 0.20 m², and a field (parallel to the axis of the coil) with a magnitude given by B = (4.0 + 3.0t²) T, where t is in s. What is the potential difference, V_A  V_C, at t = 3.0 s?
 
   

   
  a.
  7.2 V
   
  b.
  +7.2 V
   
  c.
  4.8 V
   
  d.
  +4.8 V
   
  e.
  12 V
