Question

15. A particle is moving in a circular path of radius r. After completing one round of the path, what would be the total distance covered by the particle and displacement?

Answer 1

Answer:

after completing one round of the circle the distance of particle will be the circumference of the circle

$distance = 2\pi \: r$

displacement is the shortest distance between the initial and final point

as the particle is back to its initial position

therefore displacement of the particle will be zero
