An object has moved through a distance. Its displacement

• A. Must be zero
• B. May be zero
• C. Must not be zero
• D. Cant say

Answer 1

Answer: (B)

May be zero

An object which has moved through a distance can have zero displacement.
Example:
When a person, walking along a circular path, returns back to the starting point, after completing a circle, his displacement is zero, but he covers a distance $2\pi r$, where '$r$' is the radius of circular path.
