The two strongest forces that protons in a nucleus exert on each other are
A)the weak nuclear and electromagnetic forces.
B)the weak nuclear and the gravitational forces.
C)the electrostatic and the gravitational forces.
D)the strong nuclear and the electrostatic forces.

Question

Quizplus · Accepted Answer

The strong nuclear force is the strongest force between protons in a nucleus, and it is responsible for binding the nucleus together. The electrostatic force, or Coulomb force, is the force between electrically charged particles, and it is the second strongest force between protons in a nucleus. Therefore, choice D, the strong nuclear and electrostatic forces, is the best answer.
