A hollow cylinder of mass

m

made heavy at its bottom is floating vertically in water. It is tilled from its vertical position through an angle

\theta

and is left. The restoring force acting on it is

View answer and explanation

Correct option: C

m\mathrm{g}\left[ {\frac{1}{{\cos \mathrm{\theta }}} - 1} \right]

Option C (

m\mathrm{g}\left[ {\frac{1}{{\cos \mathrm{\theta }}} - 1} \right]

) is correct because the restoring force is related to the change in the center of buoyancy and the resulting torque.

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
