Laws of Electrostatics
First law: Like charges of electricity repel each other, whereas unlike charges attract each other.
Second law:According to this law, the force exerted between two point charges
i) is directly proportional to the product of their strengths.
ii) is inversely proportional to the square of the distance between them. and
iii) is inversely proportional to the absolute permittivity of the surrounding medium.
This is known as Coulomb's Law
