Question

A cyclist moves from a certain point X and goes round a circle of radius 'r' and reaches Y, exactly at the other side of the point.Y, as shown in Fig.2.9. The displacement of the cyclist would be equal to :

• A. $\pi r$
• B. $2\pi r$
• C. $2r$
• D. $2\pi /r$

Answer 1

The correct option is C $2r$

Displacement is defined as the shortest path travelled between the initial and final position which is equal to the diameter of the circular track.

Displacement $=2r$
