Move the balloon towards sweater and then towards wall and observe the phenomenon of electrostatics.

Electrostatics : A study of charges at rest is called as electrostatics.

In our day to day life we come across various object which is made up of atom . Atom consist of positively Charged Protons and Negatively Charged Electrons which revolve around the atom. This charges shows various characteristics when they are at rest as well as when they are in motion. In this chapter we are going to deal with charges at rest.

In earlier class we have seen various method of charging a body such as 

1) Conduction 

2) Induction  

Gauss Law

Gauss Law : The flux of the net electric field through a closed surface equals the net charge enclosed by the surface divided by ε0.  . It is a powerful tools which helps us to find total electric flux coming out of the closed surface  .

Mathematically it is given by

                                                        ∅ = q/ε_{0           ---------(1)}

                                                            _OR

                                                                   ∅ = ∫ E .ds ----------(2)

Where  ∅ is the total flux and q is the charge enclosed within that surface .
