Explain the phenomenon of induction that was studied in thisactivity (bringing a negatively charged plastic rod near anuncharged non-metal-coated styrofoam ball that is hanging freelyand an uncharged metal-coated styrofoam ball that is hanging). Forexample, explain how a metal conductor such as a hanging ball ofaluminum foil can be attarcted to a charged insulator even thoughthe ball of foil has no net charge so that is is electricallyneutral. Can two metal balls with no net charge attract each other?Explain. Can the process of induction cause a neutral conductor tobe repelled from a charged insulator? Explain.
Thank you very much :)
