(a) A conductor having cavity C is charged as shown in Fig. What is electricfied inside the cavity ? Does the result depend upon the shape and size of the cavity ?

(b) Can Gauss's law tell us exactly where teh charge is located inside the Gaussian surface ?

Explanation

(a) It is known that electric charges reside always on the surface fo conductors only. Inside the conductors , charge is zero. The result is independent of the shape and size of the cavity will always be zero irrespective fo the size of the cavity.
(b) Gauss's law cannot determine the position of charge. This is because, acccording to Gauss's Law, electric flux over a Gaussian surface in vacumm is `1//in_(0)` times the charge enclosed inside the surface . Thus Gauss's law explains that the charge is inside the closed surface , and for every position of the charge inside teh surface, the electric flux is the same. Hence Gauss's Law. fails to specify the position of charge inside the closed surface.
