Question

Which of the following best provides evidence that there is a nuclear strong force? a. Scientists have observed that neutrons have a very sticky surface. This stickiness produces a strong force. b. Scientists can pull on individual nucleons, and feel the resistance. This resistance is caused by the strong force. c. Scientists have seen that multiple protons that close together exert very strong electrical forces. There must be a very strong force to hold them together. d. Scientists have seen that protons and neutrons are electrically attached to each other. This is the strong force.

Explanation / Answer

D) Scientist have seen that protons and neutrons are electrically attached to each other.This is the strong force.

This is the correct evidence.

The strong nuclear force is created between nucleons(protons,which carry positive charge and neutrons which carry no charge. These particals collectively called as nucleons)by the exchange of particle called mesons.This exchange is similar to hitting back and forth like ping pong balls.As long as this mesons exchange can happen,the strong force is able to hold the participating nucleons together.
