Question

What is an electrostatic charge?

Answer 1

1. Study of stationary electric charges at rest is known as electrostatics.
2. Electrostatic charge is a point charge that creates an electric field around it.
3. Electrostatic charge is a scalar quantity.
4. There are two types of electric charge:
   3.1 positive charge
   3.2 negative charge
5. The unit of charge is Coulomb.
6. Mathematical expression for charge
   $$\begin{gathered} \mathrm{charge}=\mathrm{current}\times \mathrm{time} \\ \mathrm{Q}=\mathrm{I}.\mathrm{t} \end{gathered}$$
7. Like charges repel each other.
8. Unlike charges attract each other.
9. Electron is an example of a negative charge.
10. proton is an example of a positive charge.
11. Some properties of charges are:
    10.1 Additivity of Electric Charge
    10.2 Conservation of Electric Charge
    10.3 Quantization of Electric Charge
