Question

A and B are standing on the circumference of circle of radius 3 m subtending an angle of 60° at
centre. Initially, such that B is ahead of A. If they start moving at the same time then find after
what time they will meet if they are moving in clockwise direction with their speed 7m/s and 5m/s
respectively

Answer 1

hope it is helpful for you

Answer 2

Answer:

$\frac{\pi}{2} \: sec$

Step-by-step explanation:

AB =

$\frac{60}{360} \times 2 \times\pi \times 3$

$= \pi$

relative speed of A w.r.t. B = 7-5 = 2m/s

time required =

$\frac{\pi}{2} seconds$
