Question

Which of the following is the unit vector perpendicular to A and B?

Moderate

A

$\frac{\hat{A} \times \hat{B}}{A B \sin θ}$
B

$\frac{\hat{A} \times \hat{B}}{A B \cos θ}$
C

$\frac{A \times B}{A B \sin θ}$
D

$\frac{A \times B}{A B \cos θ}$

Solution

Unit vector perpendicular to A and B,
$\hat{n} = \frac{A \times B}{| A \times B |} = \frac{A \times B}{A B \sin θ}$
