Now consider four point charges, q1, q2, q3, and q4, that lie in the plane of the page as shown in
the diagram above. Imagine a three-dimensional closed surface whose cross section in the plane
of the page is indicated.
i. Which of these charges contribute to the net electric flux through the surface?
ii. Which of these charges contribute to the electric field at point P ?
iii. Are your answers to i and ii the same or are they different? Explain why this is so.

Expert Solution

Step 1

i. Gauss Law of electrostatics states that the electric flux through any hypothetical closed surface (irrespective of its shape and size) is equal to $\frac{1}{ε_{0}}$ times the net electric charge that the surface encloses.

Going by Gauss Law , charges q₂ and q₃ will contribute to the net electric flux through the surface.

ii) All the the charges (q₁, q₂, q₃ and q₄) will contribute to the electric field.

Electric field due to more than one charge is vector sum total of the electric field due to individual charges. We apply the principle of superposition.
