Calculate electric flux linked with a sphere of radius 1 m and charge of 1C at its centre.

Explanation

To calculate the electric flux linked with a sphere of radius 1 m and a charge of 1 C at its center, we can use Gauss's Law. Here’s a step-by-step solution:

### Step 1: Understand Gauss's Law
Gauss's Law states that the electric flux (Φ) through a closed surface is directly proportional to the charge (Q) enclosed by that surface. Mathematically, it is expressed as:
\[ \Phi = \frac{Q}{\varepsilon_0} \]
where:
