State the dimensions and SI unit of electric polarisation.

Explanation

To find the dimensions and SI unit of electric polarization, we can follow these steps:

### Step 1: Understand Electric Polarization
Electric polarization (P) is defined as the amount of electric charge per unit area. It can be mathematically expressed as:
\[ P = \frac{Q}{A} \]
where \( Q \) is the charge and \( A \) is the area.

### Step 2: Determine the Dimensions of Charge
