A metal plate of area

{10^3}\mathrm{c}{\mathrm{m}^2}

rests on a layer of oil 6 mm. thick. A tangential force of

{10^{ - 2}}\mathrm{N}

is applied on it to move it with a constant velocity of

6\mathrm{cm}{\mathrm{s}^{ - 1}}

. The coefficient of viscosity of the liquid is

View answer and explanation

Correct option: A

0.1 poise

Option A (0.1 poise) is correct because the coefficient of viscosity is calculated using the formula relating tangential force, area, velocity, and thickness of the oil layer.

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.
