Introduction:
The electrostatic force is a fundamental force of nature that is exerted by charged particles or bodies. It is responsible for many everyday phenomena, such as the attraction or repulsion of objects when rubbed together.

Explanation:
The electrostatic force can be exerted by a charged body on both another charged body and an uncharged body. Let's understand this in more detail:

1. Electrostatic force between charged bodies:
When two charged bodies are brought close to each other, they can either attract or repel each other, depending on the nature of their charges. This is known as the electrostatic force between charged bodies. The force between two charged bodies is given by Coulomb's law, which states that the force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

For example, if one body has a positive charge and the other has a negative charge, they will attract each other. Similarly, if both bodies have the same type of charge (either positive or negative), they will repel each other.

2. Electrostatic force on an uncharged body:
An uncharged body can also experience the electrostatic force when brought near a charged body. This happens because the charged body induces opposite charges on the surface of the uncharged body through a process called electrostatic induction. The induced charges create an electric field around the uncharged body, leading to an attractive or repulsive force between the charged and uncharged bodies.

For instance, if a negatively charged body is brought close to an uncharged body, the negative charges in the uncharged body will be repelled and move away from the charged body, while the positive charges will be attracted and move closer to the charged body. This redistribution of charges creates an attractive force between the two bodies.

Conclusion:
In conclusion, the electrostatic force is exerted by a charged body on both another charged body and an uncharged body. The force between charged bodies depends on their charges and distance, while the force on an uncharged body arises from the process of electrostatic induction.
