Question

a particular is revolving in a circular path of radius 1:π m it distance after completing two and half rotation​

Answer 1

Explanation:

In a circular motion when the body comes back to the original position then the displacement of the body is shortest distance between the final and the initial position of object. So the displacement is zero.

Answer 2

Answer:This may help you

Explanation:

Remember displacement refers to the shortest distance between two points and it's a vector quantity.If you travel from a point A to point B and lets suppose the path may be in any structure I.e curve,elipse,zig zag line or any other structures the displacement will be the shortest distance between these points A and B..so in the case of your problem the displacement will be zero since at the end of the trip you are at the same point from where you started..

So, displacement =0 metre

the distance you traveled would be the length you covered and the length you traveled is the circumference of the circle..

I.e distance=2*pie*R
