Question

a body moves in a circle of radius 2r what is the distance
covered and displacement of the body after 2 complete rounds?

Here,Radius of circle=2r

So circumference= $2 π \times 2 r = 4 π r$

Now,

Since the body completes 2 rounds,so total distance travelled

$2 \times c i r c u m f e r e n c e = 2 \times 4 π r = 8 π r$

Again,in this motion the initial position and final position are same.

So displacement=final position-initial position=0

a body moves in a circle of radius 2r what is the distance covered and displacement of the body after 2 complete rounds?
