MCQ
A simple pendulum executing $S.H.M.$ is falling freely along with the support. Then
  • A
    Its periodic time decreases
  • B
    Its periodic time increases
  • It does not oscillate at all
  • D
    None of these

Answer

Correct option: C.
It does not oscillate at all
c
(c) $ T = 2\pi \sqrt{\frac{l}{g}}$; for freely falling system effective $g = 0$
so $T = \infty $ or $n = 0$
It means that pendulum does not oscillate at all.
