Question

Electrical as well as gravitational effects can be thought to be caused by fields. Which of the following is true for an electrical and gravitational field ?

• A. Fields are useful for understanding forces acting through a distance.
• B. The field concept is often used to describe contact forces.
• C. There is no way to verify the existence of the force field since it is just a concept.
• D. Gravitational or electrical field does not exist in the space around an object.

Answer 1

Answer: (A)

Fields are useful for understanding forces acting through a distance.

Answer 2

Fields are indeed useful for understanding forces acting through a distance. Both electrical and gravitational fields are concepts used to describe the influence that an object with a charge or mass exerts on its surroundings. These fields exist in the space around an object and interact with other charged or massive objects, producing forces that act at a distance.
The correct statement among the options provided is: (A) Fields are useful for understanding forces acting through a distance.
