  1. Question 1

    Q1. A force vector F has a magnitude of 10 N. If another vector -F is added to it, what is the magnitude of the resultant?

    • A) 0
    • B) -10
    • C) 20
    • D) 100

    Answer: 0

    Explanation: Subtracting a vector from itself always results in a null vector with zero magnitude. Option B is wrong because magnitudes cannot be negative.
