Wind is blowing in the north direction at speed of 2 m/s which causes the rain to fall at some angle with the vertical. With what velocity should a cyclist drive so that the rain appears vertical to him:

A

`2m//s` south

B

`2m//s` north

C

`4m//s` west

D

`4m//s` south

Text Solution

Verified by Experts

The correct Answer is:
b
Horizontal component of rain's velocity will be equal to velocity of wind which is `2m//s` in north direction. If cyclist goes towards north with velocity `2m//s`, then w.r.t him rain's horizontal component of velocity will be zero, and he will see only vertical component.
