M1 Vectors-Moments Question

Hi all, I've found a tricky question which I genuinely don't get. The force F1 = (5i + 2j) N acts at the point A on a lamina where the position vector of A,
relative to a fixed origin O, is (3i – 2j) m.

(a) Calculate the magnitude and the sense of the moment of the force about O. (4 marks)
Another force F2 = (pi + qj), acts at the point B with position vector ( – i + 4j) m so that the resultant moment of the two forces, F1 and F2, about O is zero. Given also that the moment of F2 about A is 34 Ns in a clockwise sense,

(b) find the values of p and q. (

What is the distance between the origin and the point where the force is acting? And what is the perpendicular component of the force?
