A particle is moving in a circle of radius `R`.
a. What is its displacement when it covers (i) half the circle, (ii) full circle?
b. What is its distance when it comes (i) half the the circle and (ii) full circle ?.
.

Text Solution

Verified by Experts

After a half cycle movement, the initial and final position of the particle will be at the two ends of the diameter of the circular path. Hence the displacement will be 2r.
The distance traversed will be the actual path length i.e. half the circumference of the circle.
So, distance traversed = `1//2xx2pir=pir`.
