"the sum of the force from the top plate and the force from the bottom plate always equals the same amount"...as shown here:
http://www.regentsprep.org/Regents/physics/phys03/aparplate/
I mean, if a charge was placed at different places (ie distances) between 2 point charges, the net force would not be the same?
Am I using Coloumb's law incorrectly?
For example, let the charge be q and the distance between them be 4r, then if the test charge is placed half way between them, the net force would be
kq²/(2r)² + kq²/(2r)²
and if the test charge is placed at 1/4 of the distance (ie at r), then the net force would be...
kq²/(r)² + kq²/(3r)²
Any/all help/enlightenment would be appreciated. :)
