If axis of rotation of two identical cyl...

If axis of rotation of two identical cylinders, one solid and other hollow is taken as their geometrical axis. Then the ratio of radius of gyration of hollow one to that of solid is…………

A

`(1)/(2)`

B

`(1)/(sqrt(2))`

C

2

D

`sqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`("Radius of gyration of hollow cylinder")/("Radius of gyration of solid cylinder")`
`=(R)/(R//sqrt(2))=sqrt(2)`
