GEO2024
A planar, irregular shaped object has a mass of 2 kg. Its moment of inertia along the two orthogonal axis in the plane of the object are 3 kg m^2 and 4 kg m^2, respectively. The moment of inertia of the object along an axis perpendicular to the plane and passing through a point 0·5 m away from its centre of mass is represented by I. Which one among the following is the correct value of I ?
- A 7·5 kg m^2 ✓
- B 7 kg m^2
- C 5 kg m^2
- D 1 kg m^2
✓ Correct answer: (A)
