Answer #1

A.) lepton has half integer spin where as hadron( called boson) has integer spin.

B) LEPTON is truly truly element particle this is not further divided. Hadron is subdivided into many quarks.

So best choice will be " hadrons are not truly elementary particle and lepton are true elementary particle.

C) .Lepton intract with weak nuclear force while Hadron intract with strong nuclear force.

So correct choice is

"Leptons do not interact via the strong interaction, whereas hadrons"

D. )BOTH lepton and Hadron intract with gravitational force. So correct choice is

"Both leptons and hadrons do interact via the gravity interaction"

When an external magnetic field B is applied, a "spin-1" ion has 3 magnetic states with energies given Em=aBm, m=-1,0,1, where a is a constant of order a few times the Bohr magneton up = en/(2m). (Note: the notation here is quite different from that of Kittel & Kroemer who use "m" for the elementary magnetic moment which we have denoted a. In our terminology, m=ms is an integer quantum number: m=-1 labels the "spin down" state, m=0 labels...
