None of the above. A spherical conducting shell of inner radius r 1 and outer radius r 2 has a charge Q. What is the surface charge density on the inner and outer surfaces of the shell? A conducting spherical shell having inner radius a and outer radius b carries a net charge Q. If a point charge q is placed at the centre of this shell, then the surface charge density on the outer surface of the shell is given as:. A metallic spherical shell has an inner radius R 1 and outer radius R 2.

It turns out that in situations that have certain symmetries spherical, cylindrical, or planar in the charge distribution, we can deduce the electric field based on knowledge of the electric flux. In these systems, we can find a Gaussian surface S over which the electric field has constant magnitude. Note that these symmetries lead to the transformation of the flux integral into a product of the magnitude of the electric field and an appropriate area. The direction of the electric field at point P is obtained from the symmetry of the charge distribution and the type of charge in the distribution. Here is a summary of the steps we will follow:. They are. To exploit the symmetry, we perform the calculations in appropriate coordinate systems and use the right kind of Gaussian surface for that symmetry, applying the remaining four steps. A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. Thus, it is not the shape of the object but rather the shape of the charge distribution that determines whether or not a system has spherical symmetry.

Imagine for a moment that we have two neutrally-charged but otherwise arbitrary conductors, separated in space. Figure 2. Clearly there is an electric field pointing out of the former, and into the latter, with the field lines leaving and landing perpendicular to the surfaces.

The electric field of a point charge Q can be obtained by a straightforward application of Gauss' law. Considering a Gaussian surface in the form of a sphere at radius r , the electric field has the same magnitude at every point of the sphere and is directed outward. The electric flux is then just the electric field times the area of the sphere.
