Question

What is the dimaesional formula of coefficient of friction ?¿

Answer 1

The dimensional formula of coefficient of friction is given by,

$\longrightarrow\bold{\pmb{\green{[M^0 L^0 T^0]}}}$

Where,

• M = Mass
• L = Length
• T = Time

Answer 2

Or, μ = [M1 L1 T-2] × [M1 L1 T-2]-1 = [M0 L0 T0]. Therefore, the coefficient of friction is dimensionally represented as [M0 L0 T0].
