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

Protons are both positively charged, therefore the electrical forces between them will be the strongest and will determine their relative motion. Gravitational forces are negligible at this scale, nuclear forces only come into play at extremely short distance, magnetic forces on static charges are zero, and electric dipole moments are not mentioned in the scenario.
