JEE Main 2022 Physics question
Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Product of Pressure (P) and time (t) has the same dimension as that of coefficient of viscosity. Reason R : Coefficient of viscosity = Force/Velocity gradient Choose the correct answer from the options given below.
Answer: (3)
Solution
[Pressure][Time] = (Force/Area) = (Force/Area)(Distance/Velocity), which is the dimension of the coefficient of viscosity, so
