Question
Physics Question on Motion in a straight line
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
all are true
Answer
may be zero or may not be zero
Explanation
Solution
When displacement is zero, particle may be at rest, therefore, distance travelled = 0. Again, when displacement is zero, final position coincides with the initial position, distance travelled is not zero.
