NTA Abhyas JEE Main2020PhysicsOscillationsPractice
An object of mass 1 kg executes simple harmonic oscillations along the x -axis, with a frequency of 2 π H z . At the position x = 1 m , the object has a kinetic energy of 24 J . The amplitude of the oscillation is
Options
- A3 2   m
- B2 m
- C4 m
- D8 m
Correct answer
B. 2 m
Step-by-step solution
K . E . = 1 2 m ω 2 A 2 - x 2 = 24 J 1 2 × 1 × 16 A 2 - 1 = 24 A = 2 m
