From a steel wire of density ρ is suspended a brass block of density

{\rho _B}

. The extension of steel wire comes to

l

. If the brass block is now fully immersed in a liquid of density

{\rho _L}

, the extension becomes

l'

. The ratio

l/l'

will be

View answer and explanation

Correct option: D

\frac{{{\rho _B}}}{{{\rho _B} - {\rho _L}}}

Option D (

\frac{{{\rho _B}}}{{{\rho _B} - {\rho _L}}}

) is correct because the extension of the wire is proportional to the tension, which changes when the brass block is immersed in the liquid due to the buoyant force.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.

In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
