WebMar 19, 2024 · Examples of Scalar Product of Two Vectors: Work done is defined as scalar product as W = F · s, Where F is a force and s is a displacement produced by the force Power is defined as a scalar product as P = F · v, Where F is a force and v is a velocity. Notes: if two vectors are perpendicular to each other then θ = 90° , thus cos θ = cos 90° = 0 Hence a · b … WebAnswer: The scalar product of vectors a = 2i + 3j - 6k and b = i + 9k is -49. Example 2: Calculate the scalar product of vectors a and b when the modulus of a is 9, modulus of b is 7 and the angle between the two vectors is 60°. Solution: To determine the scalar product of vectors a and b, we will use the scalar product formula.
In mathematics, the quadruple product is a product of four vectors in three-dimensional Euclidean space. The name "quadruple product" is used for two different products, the scalar-valued scalar quadruple product and the vector-valued vector quadruple product or vector product of four vectors.
