Question

Quizplus · Accepted Answer

The four fundamental forces are the strong force, which holds atomic nuclei together, the weak force, which governs the decay of certain subatomic particles, the electromagnetic force, which governs the interactions of charged particles, and gravity, which governs the interactions of massive objects. Choice A correctly identifies these four forces. Choice B incorrectly includes an "electric force" which is already encompassed by the electromagnetic force. Choice C incorrectly includes a "nuclear force" which is actually a combination of the strong and weak forces, and a "tidal force" which is not considered a fundamental force. Choice D also incorrectly includes an "electric force" and a "magnetic force" which are both encompassed by the electromagnetic force, and does not include the weak force.
