Scalar product is also called:

Explanation

(a) Cross product: The cross product is a different operation than the scalar product. It is used to calculate a vector that is perpendicular to both input vectors, not the scalar product. So, option (a) is not the correct one. (b) Vector product: Similar to option (a), the vector product is another name for the cross product, not the scalar product. It calculates a vector, not a scalar. Therefore, option (b) is not the correct one. (c) Base vector: Base vectors, also known as basis vectors, are used to represent the directions in a coordinate system. They are not directly related to the scalar product. So, option (c) is not the correct one. (d) Dot product: The scalar product is also called the dot product. It is a mathematical operation that takes two vectors and produces a scalar value. The dot product measures the similarity or alignment between two vectors. So, option (d) is the correct one! In summary, the scalar product is also known as the dot product.
