Electrostatics is the study of charges at rest.
Charging a body can be done by friction, induction and conduction.
Properties of charges:
o Like charges repel and unlike charges attract.
o Charges are additive in nature i.e., Q=
o Charges are quantized. i.e., Q= ± ne [n=1,2,3,… & e=1.602 X10-19 C]
o Charge in a body is independent of its velocity.
o Charge is conserved.
To measure charge electroscopes are used.
Coulomb’s law:
k=
= 9X109 Nm2
