In 1851, who founded the science of hydrodynamics with his law of viscosity, describing the velocity of a small sphere through a viscous fluid?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. George Gabriel Stokes.
In 1851, George Gabriel Stokes, a British physicist and mathematician, founded the science of hydrodynamics by formulating Stokes' Law of Viscosity. This law describes the force of viscosity on a small spherical object moving through a viscous fluid. According to Stokes’ Law, the drag force is directly proportional to the fluid’s viscosity, the sphere’s radius, and its velocity. His groundbreaking work laid the foundation for fluid dynamics and has applications in engineering, meteorology, and biological sciences.
