Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.
zero
These are forces which act in the same plane (coplanar, not coplanner!) and that their lines of action all meet at a single point.
A triangle of vectors, in which the sides are the three vectors arranged head-tail.
Two vectors: no. Three vectors: yes.
That really depends on the type of vectors. Operations on regular vectors in three-dimensional space include addition, subtraction, scalar product, dot product, cross product.
Cross product is a mathematics term when there is a binary operation on two vectors in three-dimensional space.
Cross product also known as vector product can best be described as a binary operation on two vectors in a three-dimensional space. The created vector is perpendicular to both of the multiplied vectors.

Three vectors are coplanar if they sum to zero. V1 + V2 + V3 = o means the three vectors are coplanar.
The cosine of the angle between two vectors is used in the dot product because it measures the similarity or alignment of the vectors. The dot product calculates the product of the magnitudes of the vectors and the cosine of the angle between them, resulting in a scalar value that represents the degree of alignment or correlation between the vectors.
Perpendicular means that the angle between the two vectors is 90 degrees - a right angle. If you have the vectors as components, just take the dot product - if the dot product is zero, that means either that the vectors are perpendicular, or that one of the vectors has a magnitude of zero.
A dot product is a scalar product so it is a single number with only one component. A cross product or vector product is a vector which has three components like the original vectors.
