WebE = 1 4 π ϵ 0 ρ R d θ R 2. Hence, the net electric field is along the negative y -axis and the magnitude is. E = 1 4 π ϵ 0 2 ρ R ∫ 0 π / 2 sin θ d θ = ρ 2 π ϵ 0 R. Now, finding the field at an arbitrary point may not be that easy. In fact, akhmetali has given an answer but it seems that the integral is elliptic in nature. WebFeb 2, 2024 · To find the electric field at a point due to a point charge, proceed as follows: Divide the magnitude of the charge by the square of the distance of the charge from the point. Multiply the value from step 1 with Coulomb's constant, i.e., 8.9876 × 10⁹ N·m²/C². You will get the electric field at a point due to a single-point charge.
