MHT CET 2024 Physics question
A simple pendulum of length 'L' has mass 'M' and it oscillates freely with amplitude 'A'. at extreme position, its potential energy is [g = acceleration due to gravity]
Answer: (D)
Solution
At the extreme position the bob is momentarily at rest, so all its energy is potential, measured from the mean (lowest) position. If the angular amplitude is , the height gained is for small oscillations. The linear amplitude is $A
