Q. Starting position of an object is represented as x=5.1±0.2m and finishing position as y=6.9±0.3m. What will be the displacement and error in displacement?

  • (A) displacement = 1m, error = 0.5m
  • (B) displacement = 2m, error = 0.36m
  • (C) displacement = 1.8m, error = 0.36m
  • (D) displacement = 1.5m, error = 0.4m

Explanation by: Mr. Dubey
displacement between two positions represented as x±Δx and y±Δy is iy-xi and error in displacement is (Δx2 +Δy2)1/2.
