Two boys are standing at the ends A and B of a ground, where AB = a. The boy at B starts running in a direction perpendicular to AB with velocity v1​. The boy at A starts running simultaneously with velocity v and catches the other boy in a time t, where t is (1) A/ (V2 + V12)1/2 (2) A/ (V + V1) (3) A/(V – V1) (4) ( A2/ (V2- V12)1/2

(A) \(\begin{array}{l}frac{a}{sqrt{v^{2}+}v^{2}_{1}}\end{array} \) (B) \(\begin{array}{l}frac{a}{sqrt{v^{2}-}v^{2}_{1}}\end{array} \) (C) \(\begin{array}{l}frac{a}{v – v_{1}}\end{array} \) (D) \(\begin{array}{l}frac{a}{v + v_{1}}\end{array} \) Distance covered by boy... View Article
