Official Correct Choice:
Option B: South
Concept:

Displacement vectors sum geometrically. To achieve a net zero displacement, the return vector must perfectly cancel the initial vector.

Solution:

  • Initial vector: \( +15 \text{ m} \) North.


  • To return to the exact starting point (origin), the body must travel precisely backward along the same line.


  • The opposite compass direction of North is South. Covering 15m South perfectly zeroes the displacement.


Why other options are incorrect:

More North simply adds distance. East and West create diagonal hypotenuse displacements (Pythagorean theorem).

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
