The `chi-(1//T)` graph for an alloy of paramagnetic nature is shown in Fig. The curie constance is, then

A

57K

B

`2.8 xx 10^(-3) K`

C

570K

D

`17.5 xx 10^(-3) K`

Verified by Experts

The correct Answer is:

A

`chi_(e) prop (1)/(T)`
`rArr (chi_(e))/(((1)/(T))) =` Curie constant
Slope ` = (0.4)/(7 xx 10^(-3))= 57K`
