Ncert Exercises & Solutions

What are the dimensions of $χ$ , the magnetic susceptibility? Consider an H-atom. Gives an expression for $χ$ , upto a constant by constructing a number of dimensions of $χ$ , out of parameters of the atom e, m, v, R, and $μ_{0}$ . Here, m is the electronic mass, v is electronic velocity, R is Bohr radius. Estimate the number so obtained and compare with the value of | $χ$ | $~ 10^{- 5}$ for many solid materials.
