  1. Question 1

    Q1. Given a vector A = 3i - 4j, find the unit vector in the direction of A for normalized directional analysis.

    • A) 0.6i - 0.8j
    • B) 3i - 4j
    • C) 0.6i + 0.8j
    • D) 1i - 1j

    Answer: 0.6i - 0.8j

    Explanation: The unit vector is A divided by its magnitude (5). This gives 0.6i - 0.8j. Option C is wrong because it uses the wrong signs.
