‘u₁’ and ‘u₂’ are the velocities of approach of two moving bodies in the same direction and their corresponding velocities of separation are ‘v₁’ and ‘v₂’. As per Newton's law of collision of elastic bodies, the coefficient of restitution (e) is given by

A) $${\text{e}} = \frac{{{{\text{v}}_1} - {{\text{v}}_2}}}{{{{\text{u}}_2} - {{\text{u}}_1}}}$$ B) $${\text{e}} = \frac{{{{\text{u}}_2} - {{\text{u}}_1}}}{{{{\text{v}}_1} - {{\text{v}}_2}}}$$ C) $${\text{e}} = \frac{{{{\text{v}}_2} - {{\text{v}}_1}}}{{{{\text{u}}_1} - {{\text{u}}_2}}}$$ D) $${\text{e}} = \frac{{{{\text{v}}_1} - {{\text{v}}_2}}}{{{{\text{u}}_2} + {{\text{u}}_1}}}$$
