If two circular disks of the weight and ...

If two circular disks of the weight and thickness are made from metals having different densities. Which disk, if either will have the larger moment of inertia about its central axis.

Text Solution

Verified by Experts

`I=(1)/(2)mR^(2)` or `IpropR^(2)`
`m`and thickness are same therfore, radius `R` of the material having smaller density should be more, so the moment of inertia.
