If two circular disks of having the same 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.

Explanation

To solve the problem of which disk has the larger moment of inertia about its central axis, we will follow these steps:

### Step 1: Understand the Moment of Inertia Formula
The moment of inertia \( I \) for a circular disk about its central axis is given by the formula:
\[ I = \frac{1}{2} M R^2 \]
where \( M \) is the mass of the disk and \( R \) is the radius of the disk.
