In the previous question, the angular frequency of the simple harmonic motion is omega . The coefficient of friction between the coin and the platform is mu . The amplitude of oscillation is gradually increased. The coin will begin to slip on the platform for the first time (i) at the extreme positions of oscillations (ii) at the mean position (iii) for an amplitude of (mug)/(omega^2) (iv) for an amplitude of (g)/(muomega^2)

Which of the following equation represents a simple harmonic motion ? ( omega is angular frequency, A is amplitude of oscillation and I = sqrt(-1)

A coin is placed on a horizontal platform, which undergoes horizontal simple harmonic motion about a mean position O. The coin does not slip on the platform. The force of friction acting on the coin is F. (i) F is always directed towards O (ii) F is directed towards O when the coin is moving away from O, and away from O when the coin moves towards O (iii) F=0 when the coin and platform come to rest momentarily at the extreme position of the harmonic motion (iv) F is maximum when the coin and platform come to rest momentarily at the extreme position of the harmonic motion
