Here is an important numerical based derivation for determining the momentum of a charged particle wch has been accelerated thru a pd of V volt. The result can be applied to any numerical.

Gauss Law is an important topic for electrostatic. It is applicable for homogeneous charge distribution such as (i) Linear charge density (ii) Planar charge density and (iii) volume charge density. One should remember that Coulomb’s Law is generally applicable for discrete distribution for point charges. Here I hav specifically uploaded how Gauss Law can be [...]

These derivations are important from electrostatics for ISC board examinations. Students are advised to practice thoroughly these derivations/p>
