Find the electric force between two protons separted by a distance of 1 fermi `(1fermi = 10^(15)m).` The protons in a nucleus remain at a separaton of this order.

Explanation

To find the electric force between two protons separated by a distance of 1 fermi (1 fermi = \(10^{-15}\) m), we can use Coulomb's law, which is given by the formula:

\[ F = k \frac{q_1 q_2}{r^2} \]

Where:
- \(F\) is the electric force between the charges,
