Re: [Phys-l] another capacitor problem

[Bernard Cleyet <bernardcleyet@redshift.com>]

An easily visualize analogy is to think magnets.   Surely bringing a  
third magnet near two will change the field and therefore the  
potentials of the first two.

Same w/ a planet and a satellite.  Intro. another satellite.

bc hopes he's got the analogy correct.
