Given that A and B are greater than 1. The magnitude of

\left( {\mathrm{\vec A} \times \mathrm{\vec B}} \right)

can not be

View answer and explanation

Correct option: C

more than AB

Option C (more than AB) is correct because the magnitude of the cross product is

AB\sin\theta

, and since A and B are greater than 1, the maximum value is AB, so it cannot be more than AB.
