NEET Physics Viscosity MCQ Question
Type: MCQ-numerical-Hard-Class 11
A fluid flows through a pipe and experiences a shearing stress of 0.5 N/m² with a strain rate of 0.2 s⁻¹. What is the viscosity of the fluid?
A
5 Pa s
B
0.1 Pa s
C
0.25 Pa s
D
0 Pa s
Correct Answer
Option C
Detailed Explanation
Viscosity is the ratio of shearing stress to strain rate. Using the given values, viscosity = 0.5 N/m² / 0.2 s⁻¹ = 0.25 Pa s.
