The electric charge of some dust particle is q = 4.5 nC. What is the net electric flux from this particle?

Question

The electric charge of some dust particle is q = 4.5 nC. What is the net electric flux from this particle?

𝜑_E = q enc / Eo= (4.5e-06C)/(8.85e-12 Nm^2/C^2)= 5.084e5 Nm^2/C which is incorrect. I am not sure if I've used the wrong formula?

Answer 1

You are using Gauss's Law appropriately. I believe that the error is that a nC is 10^-9 C
