NEET2008PhysicsRotational MotionActual
A thin rod of length L and mass M is bent at its midpoint into two halves so that the angle between them is 90^ . The moment of inertia of the bent rod about an axis passing through the bending point and perpendicular to the plane defined by the two halves of the rod is
Options
- A2 M L^2 24
- BM L^2 24
- CM L^2 12
- DM L^2 6
Correct answer
C. M L^2 12
Step-by-step solution
Distribution of masses about axis of rotation remain unchanged whether it is straight or bend. I= M L^2 12
