Energy gained by charge q when it is near a plate of potential V is  ( qV ) .
 
This gain in energy is in the form of kinetic energy.
 
hence we have
 
begin mathsize 14px style q space V space equals space 1 half space m space v squared end style
begin mathsize 14px style v space equals space square root of left parenthesis space 2 space cross times space q over m cross times V space right parenthesis end root end style
Above expression gives speed of charged particle if it gains energy from potenial V of plate

The plates of a parallel plate capacitor have an area of 90 cm2 each and are separated by 2.5 mm The capacitor is charged by connecting it to a 400 V supply How much electrostatic energy is stored by the capacitor? View this energy as stored in the electrostatic field between the plates, and obtain the energy per unit volume u. Hence arrive at a relation between u and the magnitude of electric field E between the plates.
