It is raining at a speed of `5m//s^(-1)` at an angle `37^(@)` to vertical, towards east.`A` man is moving to west with a velocity of `5 m//s^(-1)`.The angle with the vertical at which he has to hold the umbrella to protect himself from rain is.

A

`tan^(-1)(2)` to west

B

`tan^(-1)(2)` to east

C

`tan^(-1)(1/2)` to south

D

`tan^(-1)(1/2)` to east

Text Solution

Verified by Experts

The correct Answer is:
A

`sin 37=x/V_(R)=3/5,cos37=y/V_(R),Tan theta=(x+V_(M))/y`
