Question

A particle starts moving from point A and reaches at a point B along a semi-circular path ABC. Find the magnitude of the displacement of the particle.

Answer 1

Answer:

The displacement is the diameter.

Explanation:

If an object only moves at a semi-circular path, the the distance between the initial position and the final position will be twice its radius, so we can say that the minimum distance between the initial and the final position of an object moving in a semi-circular path will always be 2R = D.
