A coin is placed on a horizontal platform, which undergoes vertical simple harmonic motion of angular frequency \(\boldsymbol{\omega}\). The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time
- at the highest position of the platform
- at the mean position of the platform
- for an amplitude of \(\frac{g}{\omega^{2}}\)
- for an amplitude of \(\sqrt{\frac{g}{\omega}}\)
Answer
(A) at the highest position of the platform, (C) for an amplitude of g ^ 2
