Consider two particles 1 and 2 moving with constant velocities v_1^{\to} and v_2^{\to}. If r_1^{\to} and r_2^{\to} arethe radius vectors of the particles at the start, the relation between r_1^{\to},r_2^{\to},v_1^{\to} and v_2^{\to} when the two particles collide is

Correct Answer is : →r1−→r2|→r1−→r2| = →v1−→v2|→v1−→v2|

r_1^{\to}-r_2^{\to} = v_2^{\to}-v_1^{\to}

{r_1^{\to}+r_2^{\to}}/{|r_1^{\to}+r_2^{\to}|} = {v_1^{\to}+v_2^{\to}}/{|v_1^{\to}+v_2^{\to}|}

r_1^{\to}+r_2^{\to} = v_2^{\to}+v_1^{\to}

{r_1^{\to}-r_2^{\to}}/{|r_1^{\to}-r_2^{\to}|} = {v_1^{\to}-v_2^{\to}}/{|v_1^{\to}-v_2^{\to}|}
