A U tube containing two different liquid of density p and 2p

Last updated: 6/9/2023

A U tube containing two different liquid of density p and 2p is fixed vertically on a rotating table as shown in the figure Initially table is at rest and table can rotate about a vertical axis passing through the centre of the table The interface of two liquids of densities p and 2p respectively lies at the point A in a U tube at rest The height of liquid column above A is 3 where AB 2a The cross sectional area of the tube is S Now the table is whirled with angular velocity w about a vertical axis as shown in figure such 8 2 that the interface of the liquids shifts towards B by 3 then at this instant Find the force exerted by liquid of p on liquid of 2p at the interface A 2p
