Displacement Calculation:
- The person moves 30 m north
- Then 20 m towards east
- Finally 30√2 m in south-west direction
Displacement in North-South direction:
- Total north movement = 30 m
- Total south movement = 30√2 m
- Net displacement in North-South direction = 30 - 30√2 ≈ 10 m towards North
Displacement in East-West direction:
- Total east movement = 20 m
- Net displacement in East direction = 20 m
- Net displacement in West direction = 0 m
Final Displacement:
- The person's displacement from the origin is 10 m towards North and 20 m towards East.
- Using the Pythagorean theorem, the magnitude of displacement = √(10^2 + 20^2) = √(100 + 400) = √500 ≈ 22.36 m
Therefore, the person's final displacement from the origin is approximately 22.36 m, which is in the North-East direction. The correct option is (d) Zero.
- The person moves 30 m north
- Then 20 m towards east
- Finally 30√2 m in south-west direction
Displacement in North-South direction:
- Total north movement = 30 m
- Total south movement = 30√2 m
- Net displacement in North-South direction = 30 - 30√2 ≈ 10 m towards North
Displacement in East-West direction:
- Total east movement = 20 m
- Net displacement in East direction = 20 m
- Net displacement in West direction = 0 m
Final Displacement:
- The person's displacement from the origin is 10 m towards North and 20 m towards East.
- Using the Pythagorean theorem, the magnitude of displacement = √(10^2 + 20^2) = √(100 + 400) = √500 ≈ 22.36 m
Therefore, the person's final displacement from the origin is approximately 22.36 m, which is in the North-East direction. The correct option is (d) Zero.
