A charged particle (mass = 4.0 g, charge = 5.0 C) moves in a region where the only force on it is magnetic. What is the magnitude of the acceleration of the particle at a point where the speed of the particle is 5.0 km/s, the magnitude of the magnetic field is 8.0 mT, and the angle between the direction of the magnetic field and the velocity of the particle is 60?
 a. 39 km/s2
  b. 43 km/s2
  c. 48 km/s2
  d. 52 km/s2
  e. 25 km/s2

Question 2

A positively charged particle has a velocity in the negative z direction at point P. The magnetic force on the particle at this point is in the negative y direction. Which one of the following statements about the magnetic field at point P can be determined from this data?
 a. Bx is positive.
  b. Bz is positive.
  c. By is negative.
  d. By is positive.
