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$7.68 \times 10^{-19} \text{ C} \cdot \text{m}$

Easy
View SolutionAn electric dipole is placed at the origin in the direction of the $x$-axis. $A$ point $P$ is at a distance of $20 \, cm$ from the origin $O$ such that $OP$ makes an angle of $\pi/3$ with the $x$-axis. If the electric field at point $P$ makes an angle $\theta$ with the $x$-axis,then the value of $\theta$ is:
