The frequency of a simple pendulum of length 9.8 m will be
Correct answer: C. 1/2π Hertz
- A. 2 π Hertz
- B. π/2 Hertz
- C. 1/2π Hertz
- D. π/4 Hertz
Explanation
The frequency of a simple pendulum depends on the ratio . When , this ratio equals 1, so the pendulum makes one oscillation every seconds. Hence, its frequency is 1/2π Hertz.

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.
