Final answer:
According to Gauss's Law, if two spherical Gaussian surfaces enclose the same charge, the electric flux through each surface will be the same, regardless of the sizes of the surfaces.
Step-by-step explanation:
To answer which spherical Gaussian surface has the larger electric flux, we need to apply Gauss's Law, which is fundamental in electromagnetism. According to Gauss's Law, the electric flux through a closed surface, also known as a Gaussian surface, is directly proportional to the charge enclosed by that surface. Therefore, if we have two spherical Gaussian surfaces enclosing the same charge, the electric flux through both will be the same, regardless of their sizes or any other factors that do not affect the amount of enclosed charge.
In the context of the information provided about spherical surfaces and point charges, if Surface A and Surface B both enclose the same charge and are centered around it, irrespective of their radii, then both surfaces have the same electric flux (Option 3) since no distinction has been made about them enclosing different amounts of charge. This equivalence in flux through different surfaces, as long as they enclose the same charge, is one of the key insights provided by Gauss's Law.
