Question on magnetic attraction and repulsion?

AI Thread Summary
The discussion centers on finding a formula to calculate the acceleration of same-charge particles repelling each other and oppositely charged particles attracting each other, considering field intensity and mass. Participants reference Coulomb's law as a potential solution, which describes the electrostatic force between point charges. There is clarification that Coulomb's law specifically applies to point charges, which aligns with the original inquiry. The exchange highlights the importance of understanding the context of electrostatic forces in relation to particle interactions. Overall, the conversation effectively addresses the user's question about acceleration in electrostatic scenarios.

This is going to be quite hard to phrase but here goes.

Is there a formula/equation to find the acceleration of two of the same-charge particles, away from each other, taking into account field intensity and mass?

And the same question for attraction between two oppositely charged particles?

Thanks.

Aren't you talking about point charges?
 
Oh sorry, I am! Thanks, this is just what I was looking for.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
