Question

starting from the point A an object covers a circular path of radius 7metre and returns to the same point . calculate the distance and displacement covered by the object . ( perimeter of the circle =2πr​

Answer 1

Explanation:

radius of the circle = 7metre

perimeter of the circle=total distance covered by the object

perimeter of the circle=2πr

=2×22/7×7

=44 metre

displacement=0

because the object returns to the same position.

Answer 2

Answer: Distance = 2*(22/7)*7= 2*22=44 m

Displacement = 0

Explanation: Since it returns to the same point it completes a circle. Therefore distance travelled is the perimeter of the circle i.e 2πr where r is the radius of the circle.

And Displacement is zero because... displacement is the shortest distance between the starting point and the end point since it returns to the same point so displacement is zero
