1. On what factors does the electrostatic force between two charges depend?

governs the electrostatic forces between two point charges. The action force is on one charge, and the reaction force is on the other, and vice versa.

There are two forms of electric forces known as . Charges that are each other, while those that are  each other.

The electrostatic force between two charges depend on the,

2. What are electric lines of force?

The electric lines of force are along which a moves in the electric field.

Electric lines of force are .

The closeness of electric field lines determines the of an electric field. The lines of force are radially for an isolated positive charge, whereas they are radially  for an isolated negative charge.

3. Define electric field.

The electric field ($$E$$) around the charge is the region in which an experiences an .

represent the of electric field. The electric field's direction corresponds to the direction of force acting on a small .

4. Define electric current and give its unit.

An electric current is generally defined as the . In other words, generate an electric current.

The SI unit of the electric current is  ($$A$$).

One ampere is defined as the amount of current flowing through any cross-section of a conductor when  of charge flows through it in .
