Susceptibility of

Mg

300\;K

1.2 \times {10^{ - 5}}

. The temperature at which susceptibility will be

1.8 \times {10^{ - 5}}

View answer and explanation

Correct option: B

200

K

Option B is correct. Using Curie's law, susceptibility is inversely proportional to temperature, so

T_2 = T_1 * (\chi_1 / \chi_2)
