Question

what is the unit vector perpendicular to the plane of vectors A vector and B vector ?
​

Answer 1

Answer:

0 then because a . b is 0 they perpendicular

Answer 2

Answer:

$\dfrac{\overrightarrow{A} \times \overrightarrow{B}}{ | \overrightarrow{A} \times \overrightarrow{B} | }$

Explanation:

• To get a vector perpendicular to two vector we use cross product.
• To get a unit vector in the direction we divide the vector obtained by the magnitude of that vector.
