The susceptibility of a magnetism at

300 \mathrm{~K}

1.2 \times 10^{-5}

. The temperature at which susceptibility increases to

1.8 \times 10^{-5}

View answer and explanation

Correct option: B

200 \mathrm{~K}

Option B (200 K) is correct because the susceptibility of a paramagnetic material is inversely proportional to the absolute temperature, following Curie's Law.
