Show that the capacitance of an insulated spherical conductor is directly proportional to the radius of the conductor.

Explanation

To show that the capacitance of an insulated spherical conductor is directly proportional to the radius of the conductor, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Capacitance**:
The capacitance \( C \) of a conductor is defined as the charge \( Q \) stored per unit potential \( V \) across its surface:
\[
C = \frac{Q}{V}
