A particle (q = 4.0 C, m = 5.0 mg) moves in a uniform magnetic field with a velocity having a magnitude of 2.0 km/s and a direction that is 50 away from that of the magnetic field. The particle is observed to have an acceleration with a magnitude of 5.8 m/s2 . What is the magnitude of the magnetic field?
 a. 5.3 mT
  b. 4.9 mT
  c. 5.1 mT
  d. 4.7 mT
  e. 3.6 mT

Question 2

A particle (q = 5.0 nC, m = 3.0 g) moves in a region where the magnetic field has components Bx = 2.0 mT, By = 3.0 mT, and Bz = 4.0 mT. At an instant when the speed of the particle is 5.0 km/s and the direction of its velocity is 120 relative to the magnetic field, what is the magnitude of the acceleration of the particle?
 a. 33 m/s2
  b. 17 m/s2
  c. 39 m/s2
  d. 25 m/s2
  e. 45 m/s2

Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease. When combined with hepatitis B, hepatitis C now accounts for 75% percent of all cases of liver disease around the world. Liver failure caused by hepatitis C is now leading cause of liver transplants in the United States.
