kingwinner Posted June 8, 2006 Report Share Posted June 8, 2006 1) Two charged spheres, 10.0 cm apart, attract each other with a force of magnitude 3.0x10^-6 N. What force results if an uncharged, identical sphere is touched to one of the spheres and is then taken far away? 2) What is static electricity? Why and in what way is static electricity "static"? Must electrostatic forces be repulsive? Can electrostatic forces ever be attractive? Thanks for replying! Quote Link to comment Share on other sites More sharing options...
Roadam Posted June 8, 2006 Report Share Posted June 8, 2006 1. The sphere you touch has then only half the charge and so the repulsive force is one for quarter smaller.2. Thats the think we just been doing. Forces beetwen static charges. And of course charges are positive and negative, + and + hate each other, + and - cant be apart.

kingwinner Posted June 9, 2006 Author Report Share Posted June 9, 2006 Hi, 1) How do you know that exactly half of the charge is removed? How can this be justified mathematically? Quote Link to comment Share on other sites More sharing options...
IDMclean Posted June 9, 2006 Report Share Posted June 9, 2006 Static Equilibrium. The rate of exchange will be such that[math] q_{end} =\frac {q_1 + q_2 + q_3 + q_n...} {n}[/math] I think, though I not be sure. Quote Link to comment Share on other sites More sharing options...
Farsight Posted June 9, 2006 Report Share Posted June 9, 2006 Have a read of this here What is Electricity kingwinner. I can't vouch for its scientific correctness, but it's interesting: http://amasci.com/miscon/whatis.html Quote Link to comment Share on other sites More sharing options...
