(The arrows show the fluid flow as seen by the ball. This smooth flow only takes place for fairly slow motion, as we shall see.) If we knew mathematically precisely how the velocity in this flow pattern varied near the ball, we could find the total viscous force on the ball by finding the velocity gradient near each little

Viscous forces, like other frictional forces, impede the relative motion of nearby fluid layers. When we drop a ball in a liquid that is highly viscous in nature and when it falls then initially gravitational force acts. As it goes inside liquid then viscous force increases so its speed will be constant with time after sometimes because ...

Hint: To solve this question let us first define terminal velocity, which is the maximum velocity attained by an object when it is dropped into a column of fluid, be it liquid or gas. It depends on the density of the object dropped and the fluid on which it is dropped, dimensions of the object, the viscosity of the fluid, and the acceleration due to gravity acting on the body.
