The initial charge of a cylinder is -2.1mC, and if a charge is placed in the center of a spherical hollow with a charge of 2.3mC, the charge on the surface of the internal spherical hollow and on the outside surface of the hollow sphere are determined using Gauss’ Law.
An insulating sphere of radius a carries a total charge qq uniformly distributed over its volume. The electric field is calculated by dividing the conductor surfaces into $m$ small patches, where the $i$th patch has $q_i$ charge. The electric potential at each patch is then calculated.
Point charges, such as electrons, are fundamental building blocks of matter. According to Gauss’s law, the flux of the electric field through any closed surface, also known as a Gaussian surface, is equal to the net charge enclosed ((q_(enc)) divided by the permittivity).
The total charge of the distribution is determined by dividing the net charge inside the conducting shell by the surface charge density, which describes the total amount of charge q per unit area A. The charge on the exterior surface of the hollow sphere is 48.2 nC.
To calculate the field at an arbitrary point due to the hollow conductor, the suporposition principle is used. The total charge on the outside of the inner sphere is calculated by multiplying the surface charge density by the sphere’s surface area.
In a neutral conductor, a hollow cavity contains a +100 nC point charge, and a charged rod transfers -50 nC to the conductor. The total charge on the exterior and inside surfaces of the hollow sphere is determined by the total surface charge on the conductor’s internal surface and the total charge on its exterior surface.

In first example I understood that there is no electric flux if there is no charge inside the imaginary Gaussian surface. The cylinder is positively charged, which means that electic field is going outside of surface. So there should be electric field going towards hollow. But as per Gauss’s law there is no electric. That is the confusing part. Why we have to take Gauss’s law as granted ? Where is derivation?
Sorry but its wrong .The Gauss’ law is WRONGLY stated .. its not the product EA but the closed integral of the dot product of E and dA(or simply net FLUX) that is = Qenclosed/e. Surprised to see so many people took it at face value . And no, net charge inside a gaussian surface need not be zero for electric field to be zero . There could be electric field lines passing the gaussian surface but the net FLUX will be zero because net inward flux is gonna be equal to net outward flux … Its simple physics.
