Two protons are about 10^-10 m apart. Their relative motion is chiefly determined by: A) gravitational forces B) electrical forces C) nuclear forces D) magnetic forces E) torque due to electric dipole moments

Question

Quizplus · Accepted Answer

The dominant force between two protons at a distance of approximately $10^{-15}$ m apart is the electrical (electrostatic) force, as protons are positively charged particles and the electrical force is significantly stronger than gravitational force at such small scales. Nuclear forces are short-ranged and primarily affect particles within a nucleus, not between free protons at this distance. Magnetic forces and torque due to electric dipole moments are not the primary factors in determining the motion of protons in this context.
