A sphere of relative density

\sigma

and diameter

D

has concentric cavity of diameter

{d}

. The ratio of

\frac{{D}}{{d}}

, if it just floats on water in a tank is:

View answer and explanation

Correct option: A

\left(\frac{\sigma}{\sigma-1}\right)^{\frac{1}{3}}

Option A (

\left(\frac{\sigma}{\sigma-1}\right)^{\frac{1}{3}}

) is correct because it represents the ratio of diameters when the buoyant force equals the weight of the sphere.

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
