A coin is placed on a horizontal platform which undergoes vertical simple harmonic motoin of angular frequency \omega. The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time [AIEEE 2006]

Correct Answer is : for an amplitude of gω2

at the mean position of the platform

for an amplitude of \frac{g}{\omega^2}

For an amplitude of \frac{g^2}{\omega^2}

at the height position of the platform
