Electric charge is the property associated with matter due to which it experiences electric and magnetic effects.
Its Sl unit is coulomb (C).
There are two types of electric charges
Positive charge
Negative charge.
An object can attain positive charge by losing electrons while other can attain negative charge by gaining the electrons.
Like charges repel while opposite charges attract to each other.
The process of transferring charge from a charged body to earth called earthing.
Coulomb's Law : If q1 and q2 be two stationary point charges in free space separated by a distance r, then the force of attraction/repulsion between them,
\(F=\frac{K|q_1||q_2|}{r^ 2}\)
Where,
\(K=\frac{1}{4\piε_0}=9\times10^ 9\)
N-m2 / C2
