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=8` m
they meet when Q displace `8xx3`m
more that `implies` relative displacement`=`relative velocity`xx`time.
`8xx3=(10-2)timpliest=3`sec
