A bucket filled with water is tied to a rope of length 0.5 ~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, (g=10 ~ms ⁻² )

Options

  1. A5 ~m / s
  2. B10 ~m / s
  3. C5 ~m / s
  4. D2 5 ~m / s

Correct answer

C. 5 ~m / s

Step-by-step solution

For water not to spill out of the bucket, aligned v_ & = 5 g R & = 5 10 0.5 & =5 ~m / s aligned
