A particle moves in a circle with O as centre and AO=OB=5CM, as radius . It starts from A. Calculate : (1) the distance covered ; and the displacement , when it reaches B

Distance is the total length covered between A and B that is length of minor arc AB subtended by central angle =radius =5.
Displacement is the change in the final position from the original position,
this in our case it would be length of the chord AB = 2r=10
