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 =10 ms^(-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 =10 ms^(-2))
