An electron follows a circular path (radius = 15 cm) in a uniform magnetic field (magnitude = 3.0 G). What is the period of this motion?
 a. 0.12 ms
  b. 1.2 ms
  c. 0.18 ms
  d. 1.8 ms
  e. 1.8 ms

Question 2

An electron moves in a region where the magnetic field is uniform, has a magnitude of 60 mT, and points in the positive x direction. At t = 0 the electron has a velocity that has an x component of 30 km/s, a y component of 40 km/s, and a z component of zero. What is the radius of the resulting helical path?
 a. 4.7 mm
  b. 18 mm
  c. 3.8 mm
  d. 2.8 mm
  e. 5.7 mm

An identified risk factor for osteoporosis is the intake of excessive amounts of vitamin A. Dietary intake of approximately double the recommended daily amount of vitamin A, by women, has been shown to reduce bone mineral density and increase the chances for hip fractures compared with women who consumed the recommended daily amount (or less) of vitamin A.
