A paramagnetic material has `10^(28) atoms//m^(3)`. Its magnetic susceptibility at temperature `350K` is `2.8xx10^(-4)`. Its susceptibility at `300K` is :

A

`3.726 xx 10^(-4)`

B

`2.672 xx 10^(-4)`

C

`3.672 xx 10^(-4)`

D

`3.267 xx 10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`gamma = (C )/(T) , " "2.8 xx 10^(-4) = (C )/(350)` ...(i)
`x = (C )/(300)` ...(ii)
`x = 3.267 xx 10^(-4)`
