`x_1 and x_2` are susceptiblility of a Paramagenetic material at temperatures `T_1, K and T_2K` respectively, then

Options

A. `x_1 = x_2`
B. `x_1 T_1 = x_2 T_2`
C. `x_1 T_2 = x_2 T_1`
D. `x_1 sqrt(T_1) = x_2 sqrt(T_2)`

Answer

B

Explanation

From Curie.s Law, the susceptibility of paramagnetic substances varies inversely with temperature:
`chi_1 = (K)/(T_1) rArr K = chi_1 T_1`
`chi_2 = (K)/(T_2) rArr K = chi_2 T_2`
It must have the relation for paramagnetic substances:
`chi_1T_1 = chi_2 T_2`
