Four identical particles (mass of each = 0.24 kg) are placed at the vertices of a rectangle (2.0 m  3.0 m) and held in those positions by four light rods which form the sides of the rectangle. What is the moment of inertia of this rigid body about an axis that passes through the center of mass of the body and is parallel to the shorter sides of the rectangle?
 a. 2.4 kgm2
  b. 2.2 kgm2
  c. 1.9 kgm2
  d. 2.7 kgm2
  e. 8.6 kgm2

Question 2

Two particles (m1 = 0.20 kg, m2 = 0.30 kg) are positioned at the ends of a 2.0-m long rod of negligible mass. What is the moment of inertia of this rigid body about an axis perpendicular to the rod and through the center of mass?
 a. 0.48 kgm2
  b. 0.50 kgm2
  c. 1.2 kgm2
  d. 0.80 kgm2
  e. 0.70 kgm2
