MHT CET 2026 Physics question
A bucket containing water is revolved in vertical circle of radius r. To prevent the water from falling down, the period of revolution required is (g = gravitational acceleration)
Answer: (B)
Solution
The water just stays in the bucket at the highest point if gravity alone supplies the centripetal force: , so the minimum speed there is . The corresponding (limiting) period is \dfrac{2π r}{v}$ =
