A thin spherical shell of radius R has charge Q spread uniformly over its surface. Which of the following graphs most closely represents the electric field E(r) produced by the shell in the range `0lerltoo`, where r is the distance from the centre of the shell?

Explanation

To solve the problem of determining the electric field \( E(r) \) produced by a thin spherical shell of radius \( R \) with charge \( Q \) uniformly spread over its surface, we can follow these steps:

### Step 1: Understand the electric field inside the shell
For a uniformly charged thin spherical shell, the electric field inside the shell (for \( r < R \)) is zero. This is due to the symmetry of the charge distribution. Therefore, we can conclude:
\[ E(r) = 0 \quad \text{for} \quad r < R \]
