Question 2

Simple Harmonic Motion

Which of the following affects the period of a simple pendulum? I. Mass of the pendulum bob II. Length of the pendulum III. Acceleration due to gravity

  1. A.I, II and III
  2. B.II and III only
  3. C.I and III only
  4. D.I and II only
Show the answer and explanation

Answer: B (II and III only)

Explanation

T = 2π√(l/g), so the period depends on the length l and on g, but not on the mass of the bob.
