Two protons in an atomic nucleus are typically separated by a distance of 2 1015 m.

Question:

Two protons in an atomic nucleus are typically separated by a distance of 2 × 10−15 m. The electric repulsion force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart. What is the magnitude of the electrical force between two protons separated by 2.00 × 10−15 m?
