Question

A particle traveling in a circle of diameter 16m. Calculate the distance covered and displacement when it completes two rounds .

Answer 1

Explanation:

radius of the circle = (16/2)m = 8m

perimeter of the circle = one round = 2πr

= 2×22/7 × 8m

= 50.26 m

therefore distance covered in two rounds is 2×50.26m = 100.53m

Since the final position and the initial position of the particle is same after complete two rounds, the displacement will be 0
