MHT CET 2022 Physics question
A can filled with water is revolved in a vertical circle of radius 'r' and water just does not fall down. The time period of revolution is (g = acceleration due to gravity)
Answer: (C)
Solution
Water just does not fall at the highest point when the weight alone supplies the centripetal force: , so . The minimum (critical) speed of revolution is taken as this value, so the time period is \dfrac{2π r}{v}\dfrac${2π
