Question
The necessary condition for the bob of a pendulum to execute SHM is:
- The mass of bob should be small
- The length of the pendulum should be small
- Amplitude of oscillation should be small
- The velocity of bob should be small
Hint:
The motion of a simple pendulum is simple harmonic for small angular displacement.
The correct answer is: Amplitude of oscillation should be small
The motion of a simple pendulum is simple harmonic for small angular displacement.
So Amplitude of oscillation should be small
