Question

If displacement of a particle is zero, distance covered by it

• A. may be zero or may not be zero
• B. must be zero
• C. must not be zero
• D. must be unity

Answer 1

Answer: (A)

may be zero or may not be zero

When displacement is zero, particle may be at rest, therefore, distance traveled = 0.
But displacement can also be zero, if final position coincides with the initial position after some time, but distance traveled will not be zero.
