To find the maximum torque exerted on an electric dipole in an external electric field, we can follow these steps: ### Step 1: Understand the formula for torque on a dipole The torque (\( \tau \)) experienced by an electric dipole in an electric field is given by the formula: \[ \tau = \mathbf{p} \times \mathbf{E} \] Where \( \mathbf{p} \) is the dipole moment and \( \mathbf{E} \) is the electric field. The maximum torque occurs when the angle \( \theta \) between \( \mathbf{p} \) and \( \mathbf{E} \) is \( 90^\circ \): ...
