Question:

Consider a permanent dipole of dipole moment $\vec{p}$ in a non-uniform electric field $\vec{E}$. Which of the following option is correct?

Options:

The direction of net force is perpendicular to the direction of increasing electric field when $\vec{E}$ is parallel to $\vec{p}$.

The direction of net force is perpendicular to the direction of decreasing electric field when $\vec{E}$ is anti parallel to $\vec{p}$.

The direction of net force is in the direction of increasing electric field when $\vec{E}$ is parallel to $\vec{p}$.

The direction of net force is in the direction of increasing field when $\vec{E}$ is anti parallel to $\vec{p}$.

Correct Answer:

The direction of net force is in the direction of increasing electric field when $\vec{E}$ is parallel to $\vec{p}$.

Explanation:

The correct answer is Option (3) → The direction of net force is in the direction of increasing electric field when $\vec{E}$ is parallel to $\vec{p}$.
