    So the green vector is the resultant force of P-Q?
    There is no separate resultant force for a single vector which is what P-Q is.

    But it is the resultant force of P and -Q.

    The green vector is equal to P - Q. So you just need to find the length of the green vector using trig.

    You could say that the green vector is the resultant of P and -Q if those were the forces acting on the particle.

    The green vector is P - Q. Can you see why that is?

    And does that help?
    Yes it is making sense to me now, thanks
