The speed of the water in a river is near the surface. If the coefficient of viscosity of water is and the depth of the river is , then the shearing stress between the horizontal layers of water is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The relation of viscous force between different layers of fluid is given as, F=ηAdvdx=ηAvH, here η is the viscosity of water, A is the area, and dvdx is the rate of change of velocity with the change in position. Shearing stress = FA=ηvH.
