The uncertainty in the time period of a simple pendulum reduces by increasing its
Correct answer: C. vibration
- A. mass
- B. length
- C. vibration
- D. tension in the string
Explanation
Increasing the vibration of a simple pendulum can actually reduce the uncertainty in its time period. The time period of a pendulum can be measured more accurately when it exhibits more pronounced and consistent vibrations. By ensuring that the pendulum swings with larger amplitudes and maintains a regular oscillation pattern, the time period can be measured more precisely, reducing the uncertainty.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
