### Step-by-Step Solution: 1. **Definition of Electric Dipole Moment**: The electric dipole moment (denoted as **P**) is defined as the product of the magnitude of one of the charges (q) and the distance (d) between the two charges in an electric dipole. An electric dipole consists of two equal and opposite charges separated by a distance. \[ P = q \cdot d \] ...
