Solution

The dot product of 2 vectors will result in a scalar quantity.

Here's why:

  1. A scalar quantity is a one dimensional measurement of a quantity, like temperature, or weight.

  2. A vector quantity is a measurement that refers to both the magnitude of the medium and the direction of the movement the medium has taken.

  3. The dot product of two vectors is a type of multiplication that involves two vectors and returns a scalar. This is also known as the scalar product.

  4. When you calculate the dot product of two vectors, you multiply the vectors' magnitudes, or lengths, and the cosine of the angle between them. The result is a scalar.

  5. On the other hand, the cross product of two vectors results in another vector, not a scalar. The resultant and equilibrant of two vectors are also vectors, not scalars.

So, the dot product of 2 vectors is the correct answer.
