# Force of interaction between fast moving capacitor plates.

The plates of a square plate capacitor are separated by a very small distance and have charge $$q = 1 \mu C$$ side length $$l = 1m$$ suddenly start moving in opposite directions with equal speed $$v = 2 \times 10^8 m/s$$ as shown. Find the force experienced by one plate due to the other at this instant in Newtons.
