Electrostatics

From pg. 37

principle of conservation of charge

The net charge of an isolated system remains constant during any physical process

Principle of charge Quantisation

All charges inthe universe consist of an of interger multiple of the charge on one electron

Coulomb's Law

The magnitude of the electrostatic force exerted by one point charge on another point charge is directly proportional to the product of the magnitudes of the charges and inversly proportional to the square of the distance between them

Electric Field

The region of space in which an electric charge experiences a force.The direction of the electric field at a point is the direction that a positive test charge would move if placed at that point.

Electric field strenght at a point

the electrostatic force experienced per unit positive charge placed at a point
