Infinite line charge
E = λ / (2πε₀r)
Where: E = energy (J) / electric field (N/C), ε₀ = permittivity of free space (F/m), λ = wavelength (m) / decay constant, r = radius / distance (m)
Solved example
Given: epsilon_0 = 7, lamda = 5, r = 10
Find: E (energy (J) / electric field (N/C))
- Formula: E = λ/(2·π·ε₀·r)
- Substitute the values: E = 5/(2·π·10·7)
- Result: E = 0.011368
Answer: E = 0.011368
