Option 3 : Perpendicular to both A̅ and B̅

__Explanation:__

Vectors can be multiplied in two ways – scalar product and vector product.

**Vector product** of two vectors (A̅ and B̅) results in a vector and the resultant vector is **perpendicular to both A̅ and B̅.** It is denoted as A̅ × B̅, and

A̅ × B̅ = |A̅||B̅| sin θ

Where, θ is the angle between the two vectors A̅ and B̅

**Scalar product** of of two vectors (A̅ and B̅) results in a scalar. It is denoted as A̅ ⋅ B̅, and

A̅ × B̅ = |A̅||B̅| cos θ
