The product of vectors, where the final result is a scalar, is called as

The correct answer is: Dot product

• If the dot product of two vectors is calculated, the result should be a number, which is a scalar. Hence, the dot product is also called a  scalar product. The dot product of two vectors is written using the “dot” symbol between two vectors. If “a” and “b” are the two vectors, the dot product of “a” and “b” is written as:
• a.b =|a|× |b|× Cos(θ) Where, 
• |a| = Magnitude of vector a
• |b| = Magnitude of vector b
• Θ = Angle between vector a and vector b
