Find the electric force between two protons separated by a distance of 1 fermi (1 fermi = 10 –15 m). The protons are a nucleus remain at a separation of this order.

Question

Philoid · Accepted Answer

Given:

Charge on each proton, q₁=q₂=1.6×10^-19 C

Distance of separation,

________________________________________________

Formula used:

By Coulomb’s law, the electric force is given by:

Where ϵ₀ is the permittivity of free space

k is the electrostatic constant

q₁ and q₂ are the magnitude of charges

r is the distance of separation between the charges
