Question

The force of attraction between cation and anion is known as _______________.

Answer 1

Coulomb's law:

1. It is the fundamental law of electrostatics which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
2. Mathematically, it can be expressed as,

$F=k\frac{q_1·q_2}{r^2}$ where, $F$ is the electrostatic force, $q_1$ and $q_2$ are the two electric charges, and $r$ is the distance between the center of the two charges.

3. Coulomb’s law is used to calculate the strength of the force between two charges.

Electrostatic force:

1. The electrostatic force is also known as the Coulomb force or Coulomb interaction.
2. It's the attractive or repulsive force between two electrically charged objects.
3. Like charges repel each other while unlike charges attract each other.
4. Coulomb's law is used to calculate the strength of the force between two charges.
5. The force of attraction between cation and anion is known as the electrostatic force of attraction.
