AP and TS EAMCET Engineering Model Paper 19

A block of mass ‘m’ is placed on a horizontal platform. Coefficient of friction between the block and the platform is 0.5. If the platform makes SHM in the vertical direction with a frequency f, the maximum amplitude, without the block being detached from the platform is A1. If the same platform executes SHM in the horizontal direction with the same frequency f, the maximum amplitude is A2 without sliding of the block then
