3. Which of the following represents the correct kinetic energy that an electron would have in the scenario of nuclear beta decay, where electrons are observed to be ejected from the atomic nucleus? Suppose we assume that electrons are somehow trapped within the nucleus, occasionally escaping and being observed in the laboratory. With a typical nucleus diameter of
m, use the uncertainty principle to estimate the range of kinetic energies.
(A) 11 MeV
(B) 15 MeV
(C) 19 MeV
(D) 23 MeV
(E) 30 MeV
