Electric dipole in a uniform field
Turn a dipole in a uniform electric field and compare its torque and potential energy.
What to notice
The two forces cancel in translation but form a couple. Alignment with the field is stable.
Key relation
τ = pE sin θ; U = −pE cos θ
Try this
Compare parallel, perpendicular, and opposite orientations.
What you can change
- Magnitude of each charge: 1 to 5 nC
- Charge separation: 2 to 10 cm
- Uniform electric field: 100 to 1000 N/C
- Dipole angle to field: 0 to 180 °
