In a mass spectrometer, a single-charged particle (charge e) has a speed of 1.0  106 m/s and enters a uniform magnetic field of 0.20 T. The radius of the circular orbit is 0.020 m. What is the mass of the particle?
 
  A)
 
  3.2  10-28 kg
  B)
 
  6.4  10-28 kg
  C)
 
  1.7  10-27 kg
  D)
 
  4.5  10-27 kg
  E)
 
  3.1  10-31 kg

Question 2

In a Hall experiment a conducting strip of thickness d = 100 m is placed in a magnetic field B = 0.0 5 T. The magnetic field is perpendicular to the direction of the strip along which there is a 10-A current.
 
  What is the Hall voltage measured across the strip if the charge carrier density is 2.5  1028/m3 in this material? A)
 
  1.3 V
  B)
 
  2.5 V
  C)
 
  0.72 V
  D)
 
  6.2 V
