Question

A particle is moving in a circular path of diameter 20 m. What is its distance and displacement

covered when the particle moves from A to B? (diametrically opposite points) ​

Answer 1

Answer:

The displacement is the minimum distance between the initial position and final position.

Suppose a particle starts at a point A at the periphery of the circle and after covering half the circle, particle is at point B.

The minimum distance between points A and B is AB which is also the diameter of the circle.

Therefore, displacement after covering half the circle =Diameter=2r

Explanation:

Answer 2

Answer:

Distances is 20 meter and displacement is 0
