Question

what might happen if the strong force didnt exist?
electrons would have positive charges.
atomic nuclei would fly apart.
it would be more difficult to split atoms.
neutrons would not exist.

Explanation:

• The strong force is responsible for holding atomic nuclei (composed of protons and neutrons) together, overcoming the electrostatic repulsion between protons.
• If the strong force didn't exist, the repulsive forces between protons in the nucleus would cause the atomic nuclei to fly apart.
• The charge of electrons is a fundamental property not related to the strong force, so the first option is incorrect.
• Without the strong force, splitting atoms would likely be easier (not more difficult) as there's no force holding the nucleus together, so the third option is wrong.
• The existence of neutrons is not dependent on the strong force in the way described in the fourth option.

Answer:

B. Atomic nuclei would fly apart.
