Asked by architsrivastava02 | 22nd Apr, 2010, 01:58: PM

Expert Answer:

120° = 2π/3

Distance travelled = Arc of the circle =2πR/3

Displacement travelled = Chord of the cirlce joining initial and final positions.

Chord length can be found from using geometry,

as [(R+Rcos60)2+(Rsin60)2] = R 3, and this is the displacement.
