A paramagnetic sample shows a net magnetisation of 8 Am–1 when placed in an external magnetic field of 0.6T at a temperature of 4K. When the same sample is placed in an external magnetic field of 0.2 T at a temperature of 16K, the magnetisation will be
1
\(\frac{32}{3}Am^{-1}\)
2
\(\frac{2}{3}Am^{-1}\)
3
6 Am-1
4
2.4 Am-1.
