Q. 1 Use Gauss's law to prove following (a) Any excess charge lies on conductor must resides on its surface. (b) The electric field at the surface of a conductor is normal to the surface and has a magnitude (c) A close, hollow conductor shields it's interior from fields due to charges outside but does not shields its exterior from the fields due to charges placed inside it.
