Two men P & Q are standing at corners A ...


Two men P & Q are standing at corners A & B of square ABCD of side 8m. They start moving along the track with constant speed `2(m)/(s)` and `10(m)/(s)` respectively. Find the time when they will meet for the first time

A

`2 sec`

B

`3 sec `

C

`1 sec`

D

`6 sec`

Text Solution

Verified by Experts

The correct Answer is:
B
a=8m
They meet when Q displace 8x3 m
more that p`rArr` relative displacement
=relative velocity x time
8x3=(10-2) t , t=3sec
3 sec
