Two charges $+3.2 \times 10^{-19} \text{ C}$ and $-3.2 \times 10^{-19} \text{ C}$ placed at $2.4 \text{ Å}$ apart form an electric dipole. It is placed in a uniform electric field of intensity $4 \times 10^5 \text{ V/m}$. The electric dipole moment is

• A
  $15.36 \times 10^{-29} \text{ C} \cdot \text{m}$
• B
  $15.36 \times 10^{-19} \text{ C} \cdot \text{m}$
• C
  $7.68 \times 10^{-29} \text{ C} \cdot \text{m}$
• D
  $7.68 \times 10^{-19} \text{ C} \cdot \text{m}$
