Question

If the magnitude of vector product of two vectors is maximum, then the vectors

• A. are parallel to each other.
• B. are perpendicular to each other.
• C. are anti-parallel to each other.
• D. can have any orientation.

Answer 1

The correct option is B are perpendicular to each other.

The magnitude of vector product will be maximum when $|\sin \theta |$ will be maximum.
$\Rightarrow \theta ={90}^{\circ }$or $\theta ={270}^{\circ }$, hence, the vectors will be perpendicular to each other.
