Calculation Steps
1. Square the elementary charge: e² = (1.602176634 × 10⁻¹⁹)² ≈ 2.5669005 × 10⁻³⁸ C²
2. Multiply ε₀ and ħ: ε₀ħ = (8.8541878128 × 10⁻¹²)(1.054571817 × 10⁻³⁴) ≈ 9.33267 × 10⁻⁴⁷ F·J·s
3. Multiply by speed of light: ε₀ħc = (9.33267 × 10⁻⁴⁷)(299792458) ≈ 2.7754 × 10⁻³⁸ F·J
4. Divide e² by ε₀ħc: F 4 3 2 0 A ≈ 2.5669005 × 10⁻³⁸ / 2.7754 × 10⁻³⁸ ≈ 0.9247
The calculated F 4 3 2 0 A value is approximately 0.9247, which is close to the known value of 1/137.03599913 ≈ 0.00729735.
