1. The problem statement, all variables and given/known data It asks: Vector A has magnitude 2 and vector B has magnitude 3 with an angle between them equalling 0, 90 or 180. If the magnitude of A X B = 6, what angle/s must be between A and B? 3. The attempt at a solution Knowing that the scalar product of the two vectors can also be considered a magnitude, I went with cos(0) or cos(180). But the answer is sin(90). I understand that that's what it would be if the question is asking for a vector product, but it didn't specify. I see how their answer is also right. Am I misunderstanding something here? Or is it just known that the magnitude of the product of two vectors is the magnitude of the vector product and not of the scalar product?
