A ball of density `rho` is released from deep inside of a liquid of density `2 rho`. It will move up

A small ball of density rho_(0) is released from the surface of a liquid whose density varies with depth h as rho=(rho_(0))/2(alpha+betah) . Mass of the ball is m. Select the most appropriate one option.

The pressure inside a liquid of density rho at a depth h is :

A small ball of density 4rho_(0) is released from rest just below the surface of a liquid. The density of liquid increases with depth as rho=rho_(0)(1+ay) where a=2m^(-1) is a constant. Find the time period of its oscillation. (Neglect the viscosity effects).

A ball of density rho is dropped from a height on the surface of a non-viscous liquid of density 2rho . Choose the correct options.

A spherical small ball of density rho is gently released in a liquid of density sigma(rho> sigma) .The initial acceleration of the free fell of the ball will be

A ball of density rho is dropped from a height on the suraca of a non-visous liquid of dinsity 2rho . Choose the correct options.

A ball of density rho_(0) falls from rest from a point P onto the surface of a liquid of density rho in the time T. It enters the liquid, stops, moves up, and returns to P in a total time 3 T. neglect viscosity, surface tension and splashing find the ratio of (rho)/(rho_(0))
