Question

a body moving in a circle of radius 'r' covers 3/4 th of the circle.find the ratio of the distance to displacement.​

Answer 1

Answer:

Here radius is given which is R

so, Circumference of circle = 2pi R

Now, body covers 3/4th of radius so,

distance covered= 3/4* 2 pi R

= 3/2 pi R

Now, displacement= Root 2R [ using Pythagoras theorm]

Now, ration = 3/2 pi R/ root 2 R

= 3/root2 pi : 1

Answer 2

Answer:

answer don't know sorry
