Electrostatics

Electrostatics

1. Charge and it's properties

   • + + / - - repel & + - attract
   • Charge is transferable : Electrons held by electrostatic force = transferable Nucleons = held by nuclear force = not transferable
   • In an isolated system charge is conserved ( simple numericals of conservation )
   • Charge is quantised q = ne (e=1.6*10^-19) Electrical charge of any system is equal to integral multiple of e
     • body of charge -10C ejects 10^18 e to charge kitna CONCEPT q = ne & ejected = +ve given = -ve

2. Methods of charging : Friction Conduction Induction

3. Coulomb's Law
