Question

Correct dimension of "coefficient of viscosity" is :-

(a) $M{L}^{-1}{T}^{-1}$

(b)$ML{T}^{-1}$

(c)$M{L}^{-1}{T}^{-2}$

(d)$M{L}^{-2}{T}^{-2}$


Give the proper solution​

Answer 1

Coefficient of viscosity (η)= Fr/Av ——- F= tangential Force, Area, r= distance between the layers, v= velocity.

So dimensional formula is

M1L-1T-1

OPTION A IS CORRECT...
