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 X, as shown in Figure. The displacement of the cyclist would be

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

Answer 1

The correct option is C 2r

Displacement is the shortest distance between two points.

As X and Y are diametrically opposite, displacement is 2r.
