Physics Explanation
This simulation demonstrates the triboelectric effect when polythene is rubbed with wool:
q = n·e
m = n·mₑ
Where:
- q is the net charge (-3.0 ×10⁻⁷ C)
- n is the number of electrons transferred
- e is the electron charge (-1.6 ×10⁻¹⁹ C)
- m is the mass transferred
- mₑ is the electron mass (9.1 ×10⁻³¹ kg)
Key observations:
- Electrons transfer from wool to polythene
- Wool becomes positively charged
- Polythene becomes negatively charged
- A negligible but measurable mass is transferred
