Vectors are drawn tail-to-head on the Cartesian plane and the last one ends exactly where the first one started. What is this drawing called?
AA scaled vector sketch
BA closed vector diagram
CA single vector component
DA perpendicular axis pair
Answer & Solution
Correct answer: B. A closed vector diagram
1. Drawing tail-to-head means each new arrow starts at the head of the arrow before it.
2. If the final arrow ends at the starting point, the arrow joining start to finish has no length.
3. A resultant of zero magnitude is exactly what a closed vector diagram shows.
4. The vectors then form a closed polygon, with no gap anywhere along it.
