Question

A particle is moving on a circular path.What would be the displacement after half round of the circle?

Answer 1

Answer:

Given, after half the circle, the particle will reach the diametrically opposite point i.e., from point A to point 6. And we know displacement is shortest path between initial and final point. Hence, the displacement after half circle is 2r.

Answer 2

Answer:

after half the circle, the particle will reach the diametrically opposite point i.e., from point A to point 6. And we know displacement is shortest path between initial and final point. Hence, the displacement after half circle is 2r.
