Two parallel rail trucks run North-South. Train A moves north with a speed of `54 kmh^(-1)` and tmin B moves south with a speed of `90kmh^(-1)` The relative speed off with respect to A is

A

40 `ms^(-1)` (towards north)

B

40`ms^(-1)` (towards south)

C

10`ms^(-1)` (towards north)

D

10`ms^(-1)` (towards south)

Text Solution

Verified by Experts

The correct Answer is:
B
`v_(BA)=V_(B)-(V_(A))=90+54=144 kmh^(-1)=144xx5/18=40 m//s` (towards south)
