Coulomb's Torsion Balance Experiment
This animation reconstructs Coulomb's torsion balance apparatus, showing a suspended fiber, rotating rod, and two charged spheres. It illustrates how electrostatic repulsion twists the fiber, how the rotation angle measures force, and how force changes with distance. The formula F = k(q1q2)/r² is derived visually from the setup. Persian narration and labels make it suitable for high school physics classrooms studying electrostatics and the origins of Coulomb's law.

The prompt that made it
Coulomb's Torsion Balance Experiment: Measuring Electrostatic Force Audience: High school physics students Teaching plan: Explain Coulomb's torsion balance experiment in Persian. Start by introducing Charles-Augustin de Coulomb and the purpose of the experiment. Show a realistic 3D scientific animation of the torsion balance apparatus, including the torsion fiber, lightweight rod, charged spheres, and angular scale. Explain step by step how two charged spheres create an electrostatic force, how the force causes the rod to rotate, and how the twisting of the fiber is measured. Show that like charges repel each other and demonstrate how changing the distance between charges changes the force. Finally, explain Coulomb's law and show the formula F = k(q1q2)/r² with a clear visual explanation. Use accurate physics, Persian narration, Persian labels, and a clean classroom educational style.
