Question

What is the displacement of a particle moving is a circular path of radius R. In half the period of
revolution ?​

Answer 1

Answer:

2 Answers. (c) 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.
