Question
What is the distance travelled by a body and its displacement when it completes one revolution around a circular track with radius r?
Answer: Option D
:
D
Distance only depends on the magnitude and is equal to thetotal path covered.
Here, distance = perimeter of the circular track =2πr
Displacement depends on both magnitude and direction.
It depends only on the initial and final positions of the body and when you join initial and final points with astraight line, it gives thedisplacement of the body.
Here initial and final positions are the same, hence displacement is zero.
