Figure shows a uniform rod of length l and mass M which is pivoted at end A such that it can rotate in a vertical plane. The free end of the rod ‘B’ is initially vertically above the pivot and then released. As the rod rotates about A,
The end B of the rod will hit the ground with a linear speed:
The end B of the rod will hit the ground with a linear speed:
- \(\sqrt{2 g \ell}\)
- \(\sqrt{5 g \ell}\)
- \(\sqrt{3 g \ell}\)
- \(\sqrt{\frac{2 g}{\ell}}\)
Answer
(C) 3 g
