A rigid spherical body is spinning around an axis without any external torque. Due to change in temperature, the volume increases by 1%. What will be the percentage change in angular velocity?

Explanation

To solve the problem step-by-step, we will analyze the changes in volume, radius, moment of inertia, and angular velocity of the rigid spherical body.

### Step 1: Understand the Change in Volume
The problem states that the volume of the sphere increases by 1%. We can express this mathematically as:
\[ \frac{\Delta V}{V} \times 100 = 1\% \]
This implies:
