`X_(1)` and `X_(2)` are susceptbiltity of a paramagnetic material at temperature `T_(1)` K and `T_(2)K` 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)sqrtT_(1)=X_(2)sqrtT_(2)`

Answer

b

Explanation

According to curies law
`M = C(B_(0))/(t) Rightarrow(xB_(0))/(Mu_(0)) = C (B_(0))/(T)RightarrowXalpha(1)/(T)`
`therefore X_(1)T_(1)=X_(2)T_(2)`
