1. The problem statement, all variables and given/known data V1 and V2 are different vectors with lengths V1 and V2 respectively. Find |V1 X V2| if V1 and V2 are perpendicular. 2. Relevant equations V1 X V2 = |V1|*|V2|sin(Θ) 3. The attempt at a solution Since sin(90) = 1, V1 X V2 = |V1|*|V2|. When I input this answer it says its incorrect and the answer does not depend on V1 and V2. Is there something I'm missing?
