The size of a lead nucleus is approximately 7.1 × 10^?15 m. Use the uncertainty relation to estimate the energy of an electron that can be emitted from the nucleus, assuming that the electron was localized inside the nucleus before it emerged. Express your answer in MeV. The speed of light is 3 × 10^8 m/s and Planck’s constant is 6.63 × 10^?34 J · s. Answer in units of MeV.
