A thin uniform rod of mass and length is hanged at one end to the ground floor. It originally stands vertically and is allowed to fall to the ground. If the rod hits the ground with angular speed then the correct statement is (Assume
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
By the conservation of energy, mgL2=12Iω2, the moment of inertia of rod when the axis of rotation passing through one end is, I=ML23, it means, ω=3gL, given, L=1 m, it means, ω=3×10×1=30 rad s-1
