A bucket filled with water is tied to a rope of length $0.5 \mathrm{~m}$ and is rotated in a circular path in vertical plane. The least velocity it should have at the lowest point of circle so that water does not spill is, $\left(g=10 \mathrm{~ms}^{-2}\right)$

Options:
  • A $\sqrt{5} \mathrm{~m} / \mathrm{s}$
  • B $\sqrt{10} \mathrm{~m} / \mathrm{s}$
  • C $5 \mathrm{~m} / \mathrm{s}$
  • D $2 \sqrt{5} \mathrm{~m} / \mathrm{s}$

The correct answer is: $5 \mathrm{~m} / \mathrm{s}$
For water not to spill out of the bucket,
$\begin{aligned} v_{\min } & =\sqrt{5 g R} \\ & =\sqrt{5 \times 10 \times 0.5} \\ & =5 \mathrm{~m} / \mathrm{s}\end{aligned}$
