Easy -1.8 This is a direct recall question testing the definition that a·b = 0 implies perpendicular vectors (90°). It requires no calculation or problem-solving, just knowledge of a fundamental vector property. Even simpler than typical routine questions as it's multiple choice with only one step.
2 The two vectors \(\mathbf { a }\) and \(\mathbf { b }\) are such that \(\mathbf { a } \cdot \mathbf { b } = 0\)
State the angle between the vectors \(\mathbf { a }\) and \(\mathbf { b }\)
Circle your answer. [0pt]
