Type: MCQ-fact-Hard-Class 11
What is the relationship between the scalar product of two vectors A and B and the angle θ between them?
A
A . B = |A| |B| cos θ
B
A . B = |A| + |B| + θ
C
A . B = |A| |B| / sin θ
D
A . B = |A| - |B| cos θ
Correct Answer
Option A
Detailed Explanation
The scalar product of two vectors A and B is defined as A . B = |A| |B| cos θ, which describes how much one vector extends in the direction of another vector based on the cosine of the angle between them.
