To a person, going eastward in a car with a velociyt of `25km//hr`, a train appears to move towards north with a velocity of `25sqrt(3) km//hr`. The actual velocity of the train will be

A

25 km / hr

B

50 km /hr

C

5 km / hr

D

`5sqrt(3)` km/hr

Text Solution

Verified by Experts

The correct Answer is:
b
`V_(m)25 km hr^(-1)`
`v_(tm)=25sqrt(3) km hr^(-1)`
`v_(t)=sqrt(v_(tm)^(2))+v_(m)^(2))=50 km hr^(-1)`
