If ` vec a` is a position vector whose tip is `(1,-3)dot` Find the coordinates of the point `B` such that ` vec A B= vec a ,` if `A` has coordinates `(-1,5)dot`

Explanation

Given,

a is position vector of `(1,−3)`

`ahat=1ihat−3jhat`

Coordinates of `A=(−1,5)`

`OA=−ihat+5jhat​`


`AB=a=1i^−3j^​`

`OB−OA=1i^−3j^​`

`=OB=1i^−3j^​+OA`
