For $100, the answer is: It is a conducting container used to shield theinterior cavity from external electric fields. For perfect shielding the container must completelyenclose the cavity and the external field must be static, but in practice a non-complete enclosurewill shield against even fairly rapidly varying fields to some degree of adequacy.”What is a/an, Alex?a) Franklin stoveb) Whitney cotton ginc) Arkwright spinning framed) Carnot enginee) Faraday cage024 qmult 00915 1 1 3 easy memory: 3 ball charge exchange12. Say you had 3IDENTICALconducting balls. Call them A, B, and C. Initially, A has charge8q, B has charge 4q, and C has charge−2q. All other matter and entities are at infinity relativeto the balls. Step 1, you bring A and B into (electrical) contact while putting C at infinity and
