    Given that point A has the position vector 4i + 7j and point B has the position vector 10i + qj, where q is a constant, find
    (a) the vector AB in terms of q.
    (b) Given further that AB = 2 (square root) 13 , find the two possible values of q showing detailed reasoning in your working.

    For part a, it's effectively b-a
    From there, you can equate your equation to the value given and should probably get a quadratic to solve.
