Answer» electric field intensity due to infinite long wire is given by E = λ/2π∈₀r , where r is distance between wire and observation point. So, electric field due to 1st wire at P , E₁ = λ₁/2π∈₀x electric field due to 2nd wire at P, E₂ = λ₂/2π∈₀y So, Enet = √{E₁² + E₂²} = 1/2π∈₀ [λ₁²/x² + λ₂²/y²]½ Hence, answer is Enet = 1/2π∈₀ [λ₁²/x² + λ₂²/y²]½ |
