Question

What is vector cross product used for?

Answer 1

Vector product

1. Vector products are known as the cross-product.
2. Vector product or cross product of two vectors always gives the resultant a vector, which is calculated using the right-hand rule.
3. The formula of the cross product is given below:

$A\times B=\left|\left|A\right|\right|\times \left|\left|B\right|\right|\sin \theta$

Here, $A$ and $B$ are two vectors and $\theta$ is the angle between given vectors.

Its uses are given below:

1. Cross product is used to calculate a force's moment about a line.
2. It is used to determine the vector to a plane.
3. It is used to calculate the angle between two vectors.
