AP and TS EAMCET Engineering Model Paper 18

A massless plat form is placed on a vertical light elastic spring A particle of mass 0.1kg is dropped on the plat form form a height of 0.24m above the platform and on striking the particle the spring compressess by 0.01 m. Then the height from which another particle of mass 0.2kg is dropped to cause a compression of 0.04m
