The moment of inertia of a thin rod about an axis passing through its mid point and perpendicular to the rod is . The length of the 400 g rod is nearly: 8.5 cm 17.5 cm 20.7 cm 72.0 cm
Multiple Choice Options
- A 8.5 cm
- B 17.5 cm
- C 20.7 cm
- D 72.0 cm
Step-by-Step Verified Solution
Moment of inertia of rod = I = m _ 2 12 _ 2400 = 400 _ 2 12 _ 72 = _ 2 _ _ = 72 = 8.48 cm _ 8.5 cm
