A particle moves in a of radius R from `A` to `B`, as shown in the figure. Find the distance and displacement covered.

Distance =Length `AB=2piRxx60/360=(piR)/3`
For displacement join A and B by a straight line and the length of this line is displacement.

`OA=OB=Radius=R`
`/_OAB=/_OBA=60^(@)`
Hence, `AB=Displacement =R`
