Question: Use the uncertainty principle to show that if an electron were present in the nucleus (r 10 15m), its kinetic energy (use relativity) would

Use the uncertainty principle to show that if an electron were present in the nucleus (r ≈ 10 – 15m), its kinetic energy (use relativity) would be hundreds of MeV. (Since such electron energies are not observed, we conclude that electrons are not present in the nucleus).
