Which represents the correct dimensions of the coefficient of viscosity

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

  1. ML-2T-2
  2. MLT-1
  3. ML-1T-1
  4. ML-1T-2

Answer

F = ηA dv/dx

F → MLT-2

A → L2

dV → LT−1

dx → L

The correct option is C.
