An electric dipole of dipole moment vec p is placed in a uniform electric field vec E. Find the maximum torque experienced by the dipole.

Content Curator

When an electric dipole of dipole moment vector p is placed in a uniform electric field vector E, it experiences a torque given by the formula:

τ = p × E

where τ is the torque vector, p is the dipole moment vector, and E is the electric field vector.

The magnitude of the torque is given by:

|τ| = p E sin θ

where θ is the angle between the dipole moment vector and the electric field vector.

The maximum torque occurs when the dipole moment vector is perpendicular to the electric field vector, i.e., when θ = 90 degrees. In this case, sin θ = 1, and the magnitude of the torque is:

|τ|max = p E

Therefore, the maximum torque experienced by the dipole is equal to the product of the dipole moment and the electric field strength.
