List of top Physics Questions on Buoyancy and Floatation asked in WBJEE

A body of density '\( \rho \)' is dropped slowly on the surface of a lake of depth \( d \). If the density of the lake water be '\( \rho' \)' (\( \rho' < \rho \)) then the time taken by the body to reach the bottom of the lake is

A piece of granite floats at the interface of mercury and water. If the densities of granite, water and mercury are \( \rho, \rho_1, \rho_2 \) respectively, the ratio of volume of granite in water to that in mercury is 

A piece of granite floats at the interface of mercury and water contained in a beaker as shown in the figure. If the densities of granite, water, and mercury are \( \rho \), \( \rho_1 \), and \( \rho_2 \) respectively, the ratio of the volume of granite in water to the volume of granite in mercury is:
