Worked practice questions

As per your syllabus, the key feature that distinguishes a vector from a scalar is which?

  1. Sign
  2. Units
  3. Magnitude
  4. Direction
Show answer and solution

Correct answer: D. Direction

Your syllabus: scalar has magnitude only vector needs magnitude AND direction (and obeys triangle / parallelogram law of addition).

As per your syllabus, two vectors A and B are EQUAL if they have which property?

  1. Same magnitude and direction
  2. Same starting point in same plane
  3. Same magnitude only (any direction)
  4. Same direction only (any magnitude)
Show answer and solution

Correct answer: A. Same magnitude and direction

Your syllabus: equality requires both magnitude and direction to match. Translation does not change a vector.

As per your syllabus, the sum of a vector A and its negative -A produces which result?

  1. Vector identical to A
  2. Null vector (0)
  3. Vector of length 2A
  4. Vector identical to -A
Show answer and solution

Correct answer: B. Null vector (0)

syllabus eqn 3.3: A + (-A) = 0 (null vector). Magnitude zero; direction undefined.
