188 Chapt. 24 Gauss’s Law c) Spread (in general non-uniformly) over the surface. d) Clumped into two orbiting mass in the inside. e) All at the bottom where gravity pulls it. 024 qmult 00910 1 4 5 easy deducto-memory: Faraday cage 11. “Let’s play Jeopardy ! For $100, the answer is: It is a conducting container used to shield the interior cavity from external electric fields. For perfect shielding the container must completely enclose the cavity and the external field must be static, but in practice a non-complete enclosure will shield against even fairly rapidly varying fields to some degree of adequacy.” What is a/an , Alex? a) Franklin stove b) Whitney cotton gin c) Arkwright spinning frame d) Carnot engine e) Faraday cage 024 qmult 00915 1 1 3 easy memory: 3 ball charge exchange 12. Say you had 3 IDENTICAL conducting balls. Call them A, B, and C. Initially, A has charge 8 q , B has charge 4 q , and C has charge 2 q . All other matter and entities are at infinity relative to the balls. Step 1, you bring A and B into (electrical) contact while putting C at infinity and
