Question 16: A boy moves on a circular distance of radius R. Starting from a point A he moves to a point B which is on the other end of the diameter AB. The ratio of the distance travelled to the displacement made by him is (a) ∏/2 (b) ∏ (c) 2∏ (d) 4∏
Shortest distance between two points is always a straight line. So, shortest distance from point A to point B is AB. AB is also the diameter of the circle. ∴ Displacement is 2R.
