Show that coefficient of friction is a dimensionless quantity.

Text Solution

Verified by Experts

From definition the coefficient of friction
`mu = ("limiting friction (f)")/("normal force"(R ))`
Both f and R are forces and have the same dimension `"MLT"^(-2)`.
`:. ` Dimension of `mu = ("MLT"^(-2))/("MLT"^(-2))=1`
Hence `mu` is a dimensionless quantity
