CPL.Luke Posted April 19, 2005 Share Posted April 19, 2005 how do you calculate the amount of force the electric field departs onto the charge after it has been released from its static position math welcome Link to comment Share on other sites More sharing options...
Asimov Pupil Posted April 19, 2005 Share Posted April 19, 2005 [math]F=\frac{kq1q2}{d^2}[/math] right? Link to comment Share on other sites More sharing options...
Asimov Pupil Posted April 19, 2005 Share Posted April 19, 2005 so say you got 10 micro couloms to the right of a -2 micro couloms test charge. is this what you are getting at? Link to comment Share on other sites More sharing options...
CPL.Luke Posted April 19, 2005 Author Share Posted April 19, 2005 no thats coulombs law, Im getting at trying to calculate force from a potential. the potential energy of a system is the amount of energy required to assemble the system. its easy eneough to calculate through integration but, thats only when the system is static. when the particle moves between to points its also possible to calculate how much energy is departed onto the particle between those tow points which is the particles momentum. however I want to know how much force is applied.

swansont Posted April 19, 2005 Share Posted April 19, 2005 F = qE Link to comment Share on other sites More sharing options...
Asimov Pupil Posted April 19, 2005 Share Posted April 19, 2005 oh.......yeah what he said. Link to comment Share on other sites More sharing options...
CPL.Luke Posted April 20, 2005 Author Share Posted April 20, 2005 but what f you only have the potential V between to particles at r distance from eachother and then they are released how much force would they recieve Link to comment Share on other sites More sharing options...
ydoaPs Posted April 20, 2005 Share Posted April 20, 2005 divide the potential by the distance. Link to comment Share on other sites More sharing options...
CPL.Luke Posted April 20, 2005 Author Share Posted April 20, 2005 so F=V/r however which distance is that the distance between the to particles or the distance that they traveled after beng released? Link to comment Share on other sites More sharing options...
Asimov Pupil Posted April 21, 2005 Share Posted April 21, 2005 is that the same as [math]|E|=\frac{V}{d}[/math] Link to comment Share on other sites More sharing options...
