Calculate the moment of inertia of a rectangular bar about an axis passing through the centre and perpendicular to its length. Mass of bar is 0.2 kg and length is 10 cm

Explanation

To calculate the moment of inertia of a rectangular bar about an axis passing through its center and perpendicular to its length, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Formula**:
The moment of inertia \( I \) of a rod (rectangular bar) about an axis passing through its center and perpendicular to its length is given by the formula:
\[
I = \frac{1}{12} M L^2
