A car moves on a circular path. It completes one circle and reaches at the same point from where It had started. What is its (i) distance and (ii)displacement? Choose the correct answer for each from given options : (a) diameter (b) circumference (c) zero (d) half circumference.​

Answer 1

In one complete cycle, it comes back to its initial position, so the displacement of the object is zero.

Distance travelled = circumference of the circle = 2πr
