Question

In Stoke's law, the viscous force is not proportional to the :
a) coefficient of viscosity
b) radius of sphere
c) mass of sphere
d) terminal velocity​

Answer 1

Answer:

Explanation:

C) MASS OF THE SPHERE

Answer 2

The mathematical equation demonstrates the velocities of the small spherical particles in a fluid medium.

It is known as STOKE's LAW.

The forces are considered acting on a particular particle as it sinks through the liquid column under the action of gravity.

The formula of Stoke's law is given as :$6\pi \eta rv$

Hence, the viscous force is directly proportional to

• the radius of the sphere
• coefficient of viscosity
• the velocity of the object

The correct option is c) mass of sphere.
