Question

Which of the following is the dimension of the coefficient of friction?

• A. $\left[M^2{L}^{2}T\right]$
• B. $\left[M^0{L}^0{T}^0\right]$
• C. $\left[M{L}^2{T}^{-2}\right]$
• D. $\left[M^2{L}^2{T}^{-2}\right]$

Answer 1

The correct option is B $\left[M^0{L}^0{T}^0\right]$

Coefficient of friction is unitless and dimensionless.

Thus, $\left[M^0{L}^0{T}^0\right]$

option B is correct.
