1.	A particle is moving along a circle of radius 4m. calculate distance and Displacement when it completes 2 revolution.
Answer» Distance = 50.28mDisplacement = 0 Explanation:Distance covered = 2 revolution = 2 × Circumference of Circle ⇒ 2 × 2 π R⇒ 4 × 22/7 × 4 [RADIUS = 4m]⇒ 50.28 mDisplacement = Distance between FINAL POSITION and initial position.∴ There START and END points are same.∴ Displacement = 0
