Question

The direction of electric field intensity $\left(\vec{E}\right)$ at a point on the equatorial line of an electric dipole of dipole moment $\left(\vec{p}\right)$ is

• A. along the equatorial line towards the dipole
• B. along the equatorial line away from the dipole
• C. perpendicular to the equatorial line and opposite to $\vec{p}$
• D. perpendicular to the equatorial line and parallel to $\vec{p}$

Answer 1

Answer: (C)

The direction of electric field intensity $(\vec{E})$ at a point on the equatorial line of electric dipole of dipole moment $(\vec{p})$ is perpendicular to equatorial line and opposite to $(\vec{p})$.
