Final answer:
The displacement of a body after one complete revolution in a circular path is 0 m, because it returns to its original starting point, resulting in no change in position.
Step-by-step explanation:
If the distance covered by a body in a circular path after one revolution is 22 m, then the displacement during that revolution is actually 0 m. This is because displacement is defined as the shortest distance from the initial to the final position of the body, and in one complete revolution, the body returns to its starting point. Therefore, no matter how far the body has traveled along the circular path if it ends up at its starting point, the displacement is zero.
The discussion of the body's movement through a circular path involves differentiating between distance and displacement. Distance refers to the total path length traveled by an object, which would be the circumference of the circle in this context. Displacement, however, is a vector quantity that concerns only initial and final positions, resulting in a zero value after a full revolution.
