Q. Given that $A$ and $B$ are greater than 1. The magnitude of $(\overrightarrow{A} \times \overrightarrow{B})$ can not be
A) equal to $AB$
B) less than $AB$
C) more than $AB$
D) equal to $A/B$
Explanation
(c) $\left| \overrightarrow{A} \times \overrightarrow{B} \right| = AB\ sin\theta.$ As $sin\theta \leq 1$, therefore $AB\ sin\theta$ can not be more than $AB.$
