Question

Which of the following is necessary for a force to act between two objects?

• A. Objects must not touch each other.
• B. Objects must touch each other.
• C. Objects must be close to each other.
• D. Objects must interact with each other.

Answer 1

The correct option is D Objects must interact with each other.

A magnet can attract a piece of iron even from a distance. When we have to push an object, we have to get in contact with the object. Thus, it can be said that, for a force to come into play, two objects may or may not be in contact depending on the nature of the force. However, the two bodies must interact with each other.
