In the above example, the speed of raindrops w.r.t. the moving man, will be-

A

`10//sqrt(3)km//h`

B

`5 km//h`

C

`10 sqrt(3) km//h`

D

`5//sqrt(3) km//h`

Text Solution

Verified by Experts

Taking vertical components eq. (A) gives
` v_(r.g) cos 30^(@) = v_(r.m) " or " v_(r.m) = 20 (sqrt(3))/(2) = 10 sqrt(3)` km/h
Hence correct answer is ©
