The relation between the tool life (T) in minutes and cutting speed (V) in m/min is (where n = An exponent, which depends upon the tool and workpiece and C = A constant)

A. $${{\text{V}}^{\text{n}}}{\text{T}} = {\text{C}}$$

B. $${\text{V}}{{\text{T}}^{\text{n}}} = {\text{C}}$$

C. $$\frac{{{{\text{V}}^{\text{n}}}}}{{\text{T}}} = {\text{C}}$$

D. $$\frac{{\text{V}}}{{{{\text{T}}^{\text{n}}}}} = {\text{C}}$$

Answer: Option B
