There is one hollow sphere of radius 1 m and it contains a charge of 8.85 `muC` at its centre . Calculate the electric flux linked with the sphere per unit area . Electric flux per unit area is defined as flux density .

Explanation

To solve the problem of calculating the electric flux linked with a hollow sphere per unit area (flux density), we can follow these steps:

### Step 1: Understand the Concept of Electric Flux Density
Electric flux density (D) is defined as the electric flux (Φ) per unit area (A). Mathematically, it can be expressed as:
\[ D = \frac{\Phi}{A} \]
Where:
- \( D \) is the electric flux density,
- \( \Phi \) is the total electric flux,
