A particle moves along a circle with centre O and AO = BO = 5 cm, as radius as shown in the figure if it starts from A. The distance covered by the particle is ____ cm and the displacement is ____ cm when it reaches B. (use Π=3.14)

The distance covered by the particle is

15.7 cm

and the displacement is

10 cm

when it reaches B. (use

Π = 3.14

)
The distance covered is the length of path travelled by the particle and is given by
Distance

= π \times AO cm

= π \times 5 cm

= 3.14 \times 5 cm

= 15.7 cm

Displacement is the shortest distance between the initial and the final positions of the particle.
Displacement

= AO + BO

= 5 + 5 cm

= 10 cm

A particle moves along a circle with centre O and AO = BO $= 5 cm$ , as radius as shown in the figure if it starts from A.

The distance covered by the particle is cm and the displacement is cm when it reaches B. (use $Π = 3.14$ )
