Question

A particle moves on a circular path of radius r at half time period of rotation, the displacement of the particle will be

Answer 1

According to your question, the body movesfrom point A to point B thereby completing halfa revolution. Since distance is the length of path covered therefore it will be equal to halfthe circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distancebetween initial and final point.
