Basic property of charges is
1) charges attract and repels.
2)charges are scalar quantity because it has only magnitude not direction.
3)charges are additive in nature.
According to coulombs law
F is directly proportional to square of charges
And
F is inversely proportional to square of distance between them.
F=kQ/R^2 (k is proportionality constant)
FxR^2=Q
Si unit of force is newton N
And Of Radius is M^2
Therefore,
SI UNIT OF CHARGE IS
NM^2
