Question

Quizplus · Accepted Answer

The maximum torque on an electric dipole in an electric field occurs when the dipole moment vector ($p$) is directed perpendicular to the electric field vector ($E$). This is because torque ($\tau$) is given by $\tau = pE\sin\theta$, where $\theta$ is the angle between $p$ and $E$, and $\sin\theta$ is maximum (equal to 1) when $\theta = 90^\circ$, i.e., when $p$ is perpendicular to $E$.
