Raindrops are falling vertically with a ...

Raindrops are falling vertically with a velocity of `10m//s`. To a cyclist moving on a straight raod the raindrops appear to be coming with a velocity of `20m//s`. The velocity of cyclist is

A

`10m//s`

B

`10sqrt3m//s`

C

`20m//s`

D

`20sqrt3m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`v_(mG)=sqrt((v_(rm))^(2)-(v_(rG))^(2))=sqrt((20)^(2)+(10)^(2))=10sqrt(3) m//s`
