Answer
Correct Answer: South-West
Explanation
Introduction / Context:We chain three equal diagonal displacements on an x–y plane and compare Khader’s final position to Ramu’s origin.
Given Data / Assumptions:
- Take East = +x, North = +y.
- SE = ( +d/√2, −d/√2 ), SW = ( −d/√2, −d/√2 ), NW = ( −d/√2, +d/√2 ), where d = 100 m.
Concept / Approach:Add vectors successively, starting from Ramu at (0,0).
Step-by-Step Solution:Raju: ( +d/√2, −d/√2 ).Venu: add SW ⇒ ( 0, −2d/√2 ).Khader: add NW ⇒ ( −d/√2, −d/√2 ).x < 0, y < 0 ⇒ South-West of Ramu.
Verification / Alternative check:A vector diagram with 45° arrows confirms the final point lies down-left from the origin.
Why Other Options Are Wrong:SE/NW/North contradict the final components.
Common Pitfalls:Treating diagonal moves as axial or forgetting the √2 components.
Final Answer:South-West
