By electric flux, the electric field is 41.36 x 10⁵ N/C
We need to know about electric flux to solve this problem. Electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It can be determined as
Φ = E . S = E . Scosθ
where Φ is electric flux, E is electric field, θ is angle of surface and S is surface area.
From the question above, we know that
Φ = 5.20 × 10⁵ N.m²/C
d = 0.4 m²
r = 0.2 m²
because of maximum flux, hence (cosθ = 1)
By substituting the following parameter, we get
Φ = E . Scosθ
5.20 × 10⁵ =E . π.r²
5.20 × 10⁵ =E . π.0.2²
E = 41.36 x 10⁵ N/C
Hence, the electric field is 41.36 x 10⁵ N/C
