Find Magnitude of V1 X V2 When Vectors are Perpendicular

[henry3369]

Homework Statement

V1 and V2 are different vectors with lengths V1 and V2 respectively. Find |V1 X V2| if V1 and V2 are perpendicular.

Homework Equations

V1 X V2 = |V1|*|V2|sin(Θ)

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?

If the answer says that, are you certain the problem says perpendicular and not parallel? As formulated, you are correct.

 

[henry3369]

Yes it says perpendicular. The next question asked for parallel which is zero.

It's probably a problem with inputting the answer. Thank you anyways.
