# A body is moving along a circular path of a radius *R*. What will be the distance travelled and displacement of the body when it completes half a revolution?

Answer :

When the body is completing half a revolution of a circular path of radius r then the:-

Distance traveled in half a rotation of a circular path is equal to the circumference of semi-circle=

Displacement is known as the shortest distance between two points,

as we can see the figure the shortest distance between point A and point B is along the diameter of the circle thus displacement is **2r**
