A block is placed on a horizontal platform.. The system is making horizontal oscillations about a fixed point with a frequency of 0.5Hz. Find the maximum amplitude of oscillation if the block is not to slide on the horizontal platform? (Coefficient of friction between the block and the platform=0.2) (g=10ms^(-2))

1.	A block is placed on a horizontal platform.. The system is making horizontal oscillations about a fixed point with a frequency of 0.5Hz. Find the maximum amplitude of oscillation if the block is not to slide on the horizontal platform? (Coefficient of friction between the block and the platform=0.2) (g=10ms^(-2))
