Two boys are standing at the ends A and B of a ground, where . The boy at B starts running in a direction perpendicular to AB with velocity . The boy at A starts running simultaneously with velocity and catches the other boy in a time , where t is
Step 1: Given data
Step 2: Calculate time
From the above diagram.
Here, is the resultant velocity, is perpendicular velocity , is distance and is time.
Hence, option(A) is correct.
