If vec(A) = 3hati +4hatj and vec(B) = 7 ...

If `vec(A) = 3hati +4hatj` and `vec(B) = 7 hat I +24 hatj`, find a vector having the same magnitude as `vec(B)` and parallel to `vec(A)`.

Text Solution

Verified by Experts

`|B|=sqrt(24^(2)+7^(2))=25`
`hatA=(4hati+3hatj)/(5)`
`"required vector" ,r =25((4hati+3hatj))/(5)=20hatj+15hatj`
