Two thin concentric and coplanar spherical shells, of radii a and b `(bgta)` carry charges, q and Q, respectively. Find the magnitude of the electric field at a point distant x, from their common center for 3
(i) `0ltxlta` (ii) `alexltb` (iii) `blexltoo`

Explanation

To solve the problem, we will use Gauss's Law, which states that the electric flux through a closed surface is proportional to the charge enclosed by that surface. The electric field can be determined for three different regions based on the distance \( x \) from the center of the spherical shells.

### Step-by-Step Solution:

1. **Identify the Regions**:
- We need to find the electric field for three different cases based on the distance \( x \):
- Case (i): \( 0 < x < a \)
- Case (ii): \( a \leq x < b \)
