L> Electric Field, Spherical GeometryElectric Field of Point Charge
The electrical field of a allude charge Q deserve to be derived by a straightforward application of Gauss" regulation. Considering a Gaussian surchallenge in the create of a spbelow at radius r, the electrical field has actually the same magnitude at eextremely allude of the sphere and also is directed external. The electrical flux is then simply the electrical field times the location of the sphere.
If another charge q is inserted at r, it would experience a force so this is viewed to be constant with Coulomb"s legislation.

The electric field of a conducting sphere through charge Q deserve to be acquired by a straightforward application of Gauss" legislation. Considering a Gaussian surface in the create of a sphere at radius r > R , the electrical field has the very same magnitude at every suggest of the surchallenge and is directed exterior. The electric flux is then simply the electrical area times the area of the spherical surchallenge.
