Question

Vectors A and B have scalar product -6.00 and their vector product has magnitude +9.00. What is the angle between these two vectors?​

Answer 1

The scalar product of a and b is: a · b = |a||b| cosθ We can remember this formula as: “The modulus of the first vector, multiplied by the modulus of the second vector, multiplied by the cosine of the angle between them.”
