Question

)
The ratio of the distance and displacement in completing
a semi-circle of radius is
(a),π:2
(d) none of these
(c)2π r:1
(d)π r :1​

Answer 1

Answer:

(a) Distance:Displacement = π : 2 , is correct

Explanation:

Let the Radius of the circle be ' r ' units

As,

Distance covered in completing a Semi-circle = Circumference /2

So, Distance = (2 π r)/2 => πr

Displacement is the diameter of Circle i. e. Displacement = 2 × r

Hence, Distance:Displacement = π r : 2 r

OR

Distance:Displacement = π : 2
