A bucket filled with water is tied to a rope of length 0.5 m and is rotated in a circular path in vertical pane. The least velocity it should have at the lowest point of circle so that water dose not spill is, (𝑔 = 10 ms−2 )

Question : A bucket filled with water is tied to a rope of length 0.5 m and is rotated in a circular path in vertical pane. The least velocity it should have at the lowest point of circle so that water dose not spill is, (𝑔 = 10 ms−2 )

(A) \sqrt{5}ms^{-1}

(B) \sqrt{10}ms^{-1}

(C) 5ms^{-1}

(D) 2\sqrt{5}ms^{-1}.

Answer : option (A)

Solution :

A bucket filled with water is tied to a rope of length 0.5 m and is rotated in a circular path in vertical pane. The least velocity it should have at the lowest point of circle so that water dose not spill is, (𝑔 = 10 ms−2 )
