When it is raining vertically down, to a man walking on road the velocity of rain appears to be `1.5 times` his velocity.To protect himself from rain he should hold the umbrealla at an angle `theta` to vertical. The `tan theta=`

A

`(2)/(sqrt(5))`

B

`(sqrt(5))/(2)`

C

`(2)/(3)`

D

`(3)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
