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