A man sitting in a bus travelling in a direction from west to east with a speed of `40km//h` observes that the rain-drops are falling vertically down. To the another man standing on ground the rain will appear

A

to fall vertically down

B

to fall at an angle going from west to east

C

To fall at an angle going from east to west

D

The information given is insufficient to dicide the direction of rain.

Text Solution

Verified by Experts

The correct Answer is:
B

A man is sitting in a bus and travelling from west to east, and the raindrops are appears falling vertically down.
`v_m=` velocity of man
`v_r=`Actual velocity of rain which is falling at an angle `theta` with vertical
`v_(rm)=`velocity of rain w.r.t. to moving man
If the another man observer the rain then he will find that actually rain is falling with velocity `v_r` at an angle going from west to east.
