The maximum static friction on a body is $F = {\rm{\mu }}N$. Here, N= normal reaction force on the body ${\rm{\mu }} = $ coefficient of static friction. The dimensions of μ are

$\left[ {{\rm{ML}}{{\rm{T}}^{ - 2}}} \right]$

$\left[ {{{\rm{M}}^0}{{\rm{L}}^0}{{\rm{T}}^0}{{\rm{\theta }}^{ - 1}}} \right]$

The maximum static friction on a body is

F = \mathrm{\mu }N

. Here, N= normal reaction force on the body

\mathrm{\mu } =

coefficient of static friction. The dimensions of μ are

View answer and explanation

Correct option: C

Dimensionless

The correct answer is C (Dimensionless) because the coefficient of friction is a ratio of two forces, making it dimensionless.
