Which force is responsible for holding the protons and neutrons together within the nucleus of an atom?
A
Gravitational force
B
Strong nuclear force
C
Electromagnetic force
D
Weak nuclear force
Verified step by step guidance1
Identify the forces mentioned: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.
Recall that protons are positively charged and neutrons are neutral, so electromagnetic force causes repulsion between protons, not attraction.
Understand that gravitational force is very weak at the atomic scale and cannot hold nucleons together effectively.
Recognize that the weak nuclear force is involved in certain types of radioactive decay, not in holding the nucleus together.
Conclude that the strong nuclear force is the fundamental force responsible for overcoming the repulsion between protons and binding protons and neutrons tightly within the nucleus.
