Consider the charge configuration of a spherical Gaussian surface as shown in the figure. When calculating the flux of the electric field over the spherical surface, the electric field will be due to:
Correct answer: C. Zero
- A. q2
- B. Only the positive charges
- C. Zero
- D. +q1 and -q1
Explanation
The charge q2 is outside the Gaussian surface.External charges do not contribute to net flux through the closed surface.They may produce a field inside, but the total flux only depends on charges inside, which is zero.The flux through the spherical Gaussian surface is zero.The electric field contributions is due to +q1 ,−q1-, and the external q2 does not matter individually - only the net enclosed charge counts, which is zero.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
