Question

Electrical as well as gravitational affects can be thought to be caused by fields. Which of the following is true of an electrical or gravitational field? (A) The field concept is often used to describe contact forces (B) Gravitational or electric field does not exist in the space around an object (C) Fields are useful for understanding forces acting through a distance (D) There is no way to verify the existence of a force field since it is just a concept

Tardigrade Admin · Accepted Answer

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.

Q. Electrical as well as gravitational affects can be thought to be caused by fields. Which of the following is true of an electrical or gravitational field?

The field concept is often used to describe contact forces

Gravitational or electric field does not exist in the space around an object

Fields are useful for understanding forces acting through a distance

There is no way to verify the existence of a force field since it is just a concept
