AIEEE 2006 | Simple Harmonic Motion Question 162 | Physics

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

at the mean position of the platform

for an amplitude of $${g \over {{\omega ^2}}}$$

For an amplitude of $${{{g^2}} \over {{\omega ^2}}}$$

at the height position of the platform
