1.	Two boys are standing at the ends A and B of a ground where AB = a. The boy at B starts runing in a direction pependicular to AB with velocity v_(1).The boy at A starts runing simultaneously with velocity is v and catches the other boy is time t, where t is
Answer» `a// SQRT(V^(2)+v_(1)^(2))` `(a)/(sqrt(v^(2)-v_(1)^(2)))` `a//(v-v_(1))` `a(v+v_(1))` Answer :B
