MHT CET2017PhysicsOscillations
A simple pendulum of length L has mass M and it oscillates freely with amplitude A . At the extreme position, its potential energy is ( g = acceleration due to gravity)
Options
- AM g A 2 2 L
- BM g A 2 L
- CM g A 2 L
- D2 M g A 2 L
Correct answer
A. M g A 2 2 L
Step-by-step solution
Potential energy = 1 2 M ω 2 A 2 = 1 2 M . g L . A 2 ∴ ω = g L
