Question

Barton's pendulum experiment shows:
  1. A
    All pendulums oscillate equally
  2. B
    Pendulum with same length as driver resonates with maximum amplitude
    Correct
  3. C
    Short pendulums resonate
  4. D
    Resonance doesn't depend on length

Correct answer

Pendulum with same length as driver resonates with maximum amplitude

Explanation

In Barton's experiment, various pendulums of different lengths are driven by a heavy driver. The pendulum with the same natural frequency (same length) as the driver achieves maximum amplitude at resonance.
