The number of ways in which four molecules can be distributed in two different energy levels is :
(a)6
(b)3
(c)16
(d)8
Answer
Answer (as printed): C
Explanation
Number of energy levels $(g_{i})=2$The number of ways of distributing $=2^{N}=2^{4}=16$Number of molecules $(N_{i})=4$ (since it is not given either the particles are distinguishable or indistinguishable, therefore we will consider it as distinguishable)
