Question

An Object is moving on a circular path of radius 1m.The ratio of distance and displacement after half a circle is_______.​

Answer 1

Radius = 1 m.

Distance = 1/2 circumference of the circle = 2 x pi x 1 /2 = 3.14 cm.

Displacement = Diameter of the circle = 1 + 1 = 2.

Ratio of distance and displacement = 3.14/2 = 1.57 : 1
