MHT CET 2024 Physics question
A string of pendulum of length 'L' is displaced through from the vertical and released. Then the maximum strength of the string in order to withstand the tension as the pendulum passes through the mean position is (m = mass of pendulum, g = acceleration due to gravity)
Answer: (B)
Solution
Released from (horizontal position), the bob falls through a height . By conservation of energy, at the mean position , so . At the lowest point the net upward force provides the centripetal force: . Hence ,
