If man increases his speed to `6m//s` in the same direction , then at what angle with the vertical will he observe the rain falling ?

A

`37^(@)`

B

`53^(@)`

C

`45^(@)`

D

`60^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
(a): When man increases his speed to `6 m//s` , then velocity of rain with respect to man is an shown in the following figure :

We can see that `tan alpha =(3)/(4) rArr alpha =37^(@)`
Hence option (a) is correct .
