When a charge Q is given to a non conductuing plate & conducting plate. Find the ratio of electric field produced by them ?

Explanation

To find the ratio of the electric field produced by a non-conducting plate and a conducting plate when a charge \( Q \) is given to both, we will follow these steps:

### Step 1: Understand the charge distribution
- For a **conducting plate**, when a charge \( Q \) is given, the charge distributes itself uniformly on the surface of the conductor. This means that the electric field outside the conductor can be calculated using the surface charge density \( \sigma \).
- For a **non-conducting plate**, the charge \( Q \) is distributed throughout the volume of the plate.

### Step 2: Calculate the electric field for the conducting plate
- The electric field \( E_c \) due to an infinite conducting plane with surface charge density \( \sigma \) is given by:
