A particle (q = 5.0 nC, m = 3.0 mg) 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

Question 2

An electron has a velocity of 6.0  106 m/s in the positive x direction at a point where the magnetic field has the components Bx = 3.0 T, By = 1.5 T, and Bz = 2.0 T. What is the magnitude of the acceleration of the electron at this point?
 a. 2.1  1018 m/s2
  b. 1.6  1018 m/s2
  c. 2.6  1018 m/s2
  d. 3.2  1018 m/s2
  e. 3.7  1018 m/s2
