Which fundamental force holds protons and neutrons together in the nucleus?
AGravitational
BElectromagnetic
CStrong nuclear
DWeak nuclear
Explanation
📌 Strong nuclear force binds nucleons (protons and neutrons). At nuclear ranges (~10⁻¹⁵ m), it dominates over electromagnetic repulsion between protons. Distractor A: too weak at nuclear scales; B: would repel protons; D: involved in decay, not binding.
