Draw a plot showing variation of electric field with distance from the centre of a solid conducting sphere of radius R, having of `+` Q on its surface.

Explanation

To draw a plot showing the variation of electric field with distance from the center of a solid conducting sphere of radius \( R \) with a charge \( +Q \) on its surface, we can follow these steps:

### Step 1: Understand the Electric Field Inside the Sphere
- Inside a solid conducting sphere, the electric field is zero. This is because the charges reside on the surface of the conductor and the electric field within the conductor cancels out.

### Step 2: Determine the Electric Field on the Surface
- At the surface of the sphere (at distance \( R \)), we can use Gauss's Law to find the electric field. The electric field \( E \) at the surface is given by:
\[
