The susceptibility of a magnetism at 300...

The susceptibility of a magnetism at 300 K is ` 1.4 xx 10^(-5)`. The material is heated and at a particular temperature is susceptibility increased to ` 2. 1 xx 10^(-5)` . What is the change in temperature of the material ?

A

200 k

B

300 k

C

400 k

D

100 k

Text Solution

Verified by Experts

The correct Answer is:
D
As per curie law X=`(C )/(T)`
`therefore (x_(2))/(x_(1))=(T_(1))/(T_(2)) therefore (2.1xx10^(-5))/(1.4xx10^(-5))=(300)/(T_(2))`
`therefore` Change in temperature =`T_(1)-T_(2)=300-200=100K`
