Assertion : In a metal all the free electrons have same energy. Reason : Electrons do not obey Pauli's exclusion principle.
Options:
Answer:
C
Solution:
Assertion is correct in the sense that the free electrons occupy a single energy band. But a band has a distribution of energy. One can treat assertion as correct. But the reason is false because electrons in a metal follow Pauli's exclusion principle. It is because of this, one has different bands.
