In physics, concept of field is a model used to explain the influence that a massive body or charged particle extends into the space around itself, producing a force on another massive body or charged body placed in space. Thus, concept of field is used to explain gravitational and electrostatic phenomena.

Explanation:
Fields are useful for understanding forces acting through a distance:
- An electric field is a region around a charged object where another charged object experiences a force.
- A gravitational field is a region around a massive object where another object with mass experiences a force.
- Fields help us understand how forces can act on objects without direct contact.
- By studying fields, we can predict how objects will interact with each other even when they are not in direct contact.
Example:
- When a positive charge is placed in an electric field created by another charge, it will experience a force in the direction of the field.
- Similarly, when an object with mass is placed in a gravitational field, it will experience a force towards the massive object.
Applications:
- Understanding fields is crucial in various scientific fields like physics and engineering.
- Fields help explain phenomena such as the attraction between planets, the behavior of charged particles in an electric field, and the operation of devices like capacitors and electric motors.
Conclusion:
Understanding fields is essential for comprehending forces that act through a distance, whether they are electrical or gravitational in nature. Fields provide a powerful framework for studying interactions between objects without direct contact, making them a fundamental concept in physics.
