A man is walking on a road with a velocity 3 km/h. Suddenly rain starts falling. The velocity in vertically downwand direction. The relative velocity of man with respect to minis

A

`sqrt(13)` km/h

B

`sqrt(109)` km/h

C

`sqrt(7)` km/h

D

13km/h

Text Solution

Verified by Experts

The correct Answer is:
B
When two bodies A and B are in relative motion, the relative velocity of body A with respect to Be be obtained by impoging equal und opposite velocity of B on both A and B, so that B is brought to

Taking velocity of man as `barv_(A)` and velocity of rainas `barV_(B)` The relative velocity of man wr. to rain=`sqrt(v_(A)^(2)+v_(n)^(2))=sqrt(9+100)=sqrt(109)` km/h
