Explanation:
Given that
q₁ , q₂ , q₃
Electric field due to q₁ is E₁
Electric field due to q₂ is E₂
Electric field due to q₃is E₃
θ = 45 °
E₂ have two component
x -direction E₂ cos 45 °
y-direction E₂ sin 45 °
The resultant E
E = (E₃ + E₂ cos 45 °) i + (E₁ + E₂ sin 45 °) j
Given that
q₁ = q₂ = q₃ = q
