A vector is represented as A = i + j. What is the angle that this vector makes with the positive x-axis?
Q1. A vector is represented as A = i + j. What is the angle that this vector makes with the positive x-axis?
Answer: 45 degrees
Explanation: The angle is calculated as arctan(y/x), where arctan(1/1) equals 45 degrees. Option D is incorrect as it assumes a 90-degree orientation.
