Give a detailed example of how the exchange of a particle can result in an attractive force. (For example, consider one child pulling a toy out of the hands of another.)

The force resulting from the exchange of mass during fighting for a chair is attractive.

Step by step solution

Definition of attractive force.

Because the source of the force, electric charge, exists in two forms: positive and negative, an electrostatic force can be either attracting or repellent. The attraction between opposite charges is attractive, but the attraction between bodies with the same charge is repulsive.

Describe how attractive force is generated

As a consequence of Newton's third law of motion, when the first player exerts a force away from the second player, a reaction force will act towards the second player. Likewise, if the other player also exerts force to take away the chair from the first person, a reaction force will be applied towards the first person. So, the resultant force is attractive.

The force resulting from the exchange of particles can be either attractive or repulsive. Consider a musical chair game. If two people are fighting for a single chair, the resulting force is an attractive force. Here, the exchange of mass takes place.

Therefore, an attractive force will be generated between two people fighting for a chair.
