A body covered a distance of `L m` along a curved path of a quarter circle. The ratio of distance to displacements.

A

0.46319444444444

B

0.29930555555556

C

`11:sqrt(2)xx7`

D

`7:11sqrt(7)`

Text Solution

Verified by Experts

The correct Answer is:
C
Displacement `d=Rsqrt(2)`
distance `s=(piR)/(2)`
`therefore (s)/(d)=(piR)/(2Rsqrt(2))=(22)/(7xx2sqrt(2))=(11)/(7sqrt(2))`
