EduPoint's video: Stokes Law for Class 11 in HINDI

In this Physics video in Hindi we explained Stokes' law and derived its formula from dimentional method. This law states that when a body moves in a fluid, it experience a drag force opposite to its motion and for a spherical body this drag force is proportional to the speed of the body, the coefficient of viscosity of the fluid and the radius of the sphere. When a body falls through a fluid it drags the layer of the fluid in contact with it. A relative motion between the different layers of the fluid is set and, as a result, the body experiences a retarding force. Falling of a raindrop and swinging of a pendulum bob are some common examples of such motion. Sir George G. Stokes (1819– 1903), an Anglo - Irish scientist derived the formula for the first time in 1851.
