Which one of the following represents the correct dimensions of the coefficient of viscosity ?

Options

A. `[ML^(-1)T^(-2)]`
B. `[ML^(-2)T^(-2)]`
C. `[ML^(-1)T^(-1)]`
D. `[MLT^(-1)]`

Answer

C

Explanation

Coefficient of viscosity
`eta=("Force")/("Area"xx"Velocity gradient")`
`([MLT^(-2)])/([L^(2)][T^(-1)])=[ML^(-1)T^(-1)]`
Hence correct choice is `(c )`.
