Consider two vectors A = i + j and B = i - j. Determine the angle between these two vectors using the scalar product formula.
Q1. Consider two vectors A = i + j and B = i - j. Determine the angle between these two vectors using the scalar product formula.
Answer: 90 degrees
Explanation: The dot product is (1)(1) + (1)(-1) = 0, indicating a 90-degree angle. Option A is incorrect because the vectors are not parallel.
