A point charge Q is placed at the origin . Find the electrostatic energy stored outside the sphere of radius R centred at the origin.

Explanation

To find the electrostatic energy stored outside a sphere of radius \( R \) centered at the origin with a point charge \( Q \) placed at the origin, we can follow these steps:

### Step 1: Understand the Concept of Electrostatic Energy
The electrostatic energy \( E \) stored in a capacitor or a system of charges can be calculated using the formula:
\[ E = \frac{1}{2} \frac{Q^2}{C} \]
where \( C \) is the capacitance of the system.
