Question

If a person could fly non stop around the equator of earth and reaches back at initial point, the displacement is

• A. 2π radius of earth
• B. 2π (radius of earth)²
• C. diameter of earth
• D. zero

Answer 1

The correct option is D

zero

1. Displacement is the length between two locations measured along the shortest path connecting them.
2. If a body moves such that finally it arrives at the initial point, then the displacement is zero while distance is finite.
3. Here, a person flew around the equator of earth and reached back at the initial point, so the displacement is zero.

Hence, if a person could fly non-stop around the equator of earth and reaches back at initial point, the displacement is zero.

Hence, option D is correct.
