Question

The electric dipole moment \[\vec{p}\] is defined mathematically as:

Options

• \[\vec{p} = \frac{q}{2a}\]

• \[\vec{p} = q \cdot a\]

• \[\vec{p} = q \cdot 2a\]

• \[\vec{p} = q^2 \cdot 2a\]

Answer 1

The electric dipole moment is defined as the product of the magnitude of either charge and the separation distance between them. For charges ±q separated by distance 2a, the dipole moment is \[\vec{p} = q \times 2a\]. The SI unit is Coulomb-metre (C·m), and its direction is from the negative charge toward the positive charge.
