A boat is moving with a velocity `3 hat i+ 4hat j` with respect to ground. The water in the river is moving with a velocity `-3 hat i - 4 hat j` with respect to ground. The relative velocity of the boat with respect to water is.

A

`6hati+8hatj`

B

`8hatj+6hatj`

C

`6hati+6hatj`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A

`vecV_(b)=3hati+4hatj, vecV_(w)=-3hati-4hatj`
`vec(V_(b//w))=vecV_(b)-vecV_(w)=6hati+8hatj`
