If the Fermi energy of a neutron inside a nucleus is 38 MeV,estimate the maximum speed with which it moves around inside the nucleus.

Question

Quizplus · Accepted Answer

The maximum speed with which a neutron moves inside a nucleus can be estimated using the relation E = (1/2)mv^2, where E is the Fermi energy, m is the mass of the neutron, and v is its velocity. Solving for v, we get v = sqrt(2E/m) = sqrt(2 * 38 MeV / 1.67493 x 10^-27 kg) = 0.29 x 10^9 m/s, which is approximately 30% of the speed of light (c). Therefore, the correct answer is D.
