To what potential must a insulated sphere of radius 10 cm be charged so that the surface density of charge is equal of ` 1 muC//m^ 2 `.

Explanation

To find the potential to which an insulated sphere of radius 10 cm must be charged so that the surface charge density is equal to \(1 \, \mu C/m^2\), we can follow these steps:

### Step 1: Understand Surface Charge Density
Surface charge density (\(\sigma\)) is defined as the charge (\(Q\)) per unit surface area (\(A\)):
\[ \sigma = \frac{Q}{A} \]
