Falling Ball Viscometer
A sphere of known density and diameter is dropped into a large reservoir of the unknown fluid. At steady state, the viscous drag and buoyant force of the sphere is balanced the gravitational force. In this experiment, the speed at which a sphere falls through a viscous fluid is measured recording the sphere position as a function of time.

Terminal velocity of spheres in water
The terminal velocity of an object falling in a fluid has been measured and reported in many physics teaching articles, most commonly using a ball falling in oil or glycerine [] or using a paper cone falling in air [2, 3].At very low fall speeds in a viscous fluid such as oil or glycerine, where the Reynolds number is less than about 10, the drag force is proportional to the velocity …

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 ...

So, the correct answer is "Option A". Note: The drag force on an object falling through a liquid is given by the Stokes' law. Three forces act on a body falling through a liquid – the buoyant force, the drag force and the gravitational force.

Dropping the Ball
(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

To make it simple, we take a sphere. If we use a very viscous liquid, such as glycerin, and a small sphere, for example a ball bearing of radius a millimeter or so, it turns out experimentally that the liquid flows smoothly around the ball as it falls, with a flow pattern like: (The arrows show the fluid flow as seen by the ball.
