Revision 6584467 of "Electrodynamic force" on simplewiki

:<math>F=Q E</math>
==Application==
===2 pont charges of different polarity===
The force of attraction between 2 charges of different polarity that has the same charge's magnitude
:<math>F = K \frac{Q^2}{r^2}</math> . (<math>Q_+ = Q_-</math>)

The force of attraction between 2 charges creates an Electric Field (a field of Electric force  lines ) around 2 charges that has a magnitude
:<math>E = \frac{F}{Q} = K \frac{Q}{r^2}</math>
===Capacitor===
:<math>V = E d</math>
:<math>E = \frac{V}{d}</math>
