A cylindrical block of density p is partially immersed in a liquid of density 3p.The plane surface of the block remains parallel to the surface of the liquid.The height of the block is 60cm.The block performs SHM when displaced from its mean position(use: g=9.8 m/s^2).which are true?
- the maximum amplitude is 20cm
- the maximum amplitude is 40cm.
- the timeperiod will be 2pi/7
