Question

A body is travelling along a circular path of radius 7m. While it reach diametrically opposite end in its first rotation .Find distance and displacement​

Answer 1

Answer:

Explanation:

A body is moving along a circular path of radius r What will be the distance covered and the displacement of the body after half a revolution

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