Question

A particle is moving in a circular 1 poin
path of radius r. The
displacement after half a circle
would be:
O Zero
Ο πη
O 21
O
2rir​

Answer 1

Answer:

The answer will be 2r.

After the particle covers half path of the circle, the displacement can be easily calculated by measuring the distance between initial and final points. Displacement after half circle = AB=OA + OB Hence, the displacement after half circle is 2r.
