A Christmas ornament made from a thin hollow glass sphere hangs from a small hook at its surface. It is observed to oscillate with a frequency of 2.50 Hz in a city where g = 9.80 m/s2.
 
  What is the radius of the ornament? The moment of inertia of a hollow sphere of mass M and radius R about a point on its edge is 5MR2/3.
  A) 1.84 cm
  B) 3.68 cm
  C) 2.38 cm
  D) 3.98 cm
  E) 4.69 cm

Question 2

A thin hoop is supported in a vertical plane by a nail. What should the radius of the hoop be in order for it to have a period of oscillation of 1.00 s? The moment of inertia of a hoop of mass M and radius R about a point on its rim is 2MR2.
 
  A) 0.0154 m
  B) 0.0621 m
  C) 0.124 m
  D) 0.1876 m
