Total Attempts: 3
Accuracy Rate: 33.3%
Step-by-Step Solution
Displacement is the shortest straight-line distance between the initial and final positions. After completing half a circle, the particle is at the opposite end of the diameter. Therefore, the magnitude of displacement is equal to the diameter of the circular path, which is 2r.
