The susceptibility of tungsten is \(6 \cdot 8 \times 10^{-5}\) at temperature \(300 \mathrm{~K}\). The susceptibility at temperature \(400 \mathrm{~K}\) is
- A \(5 \cdot 1 \times 10^{-5}\)
- B \(6 \cdot 8 \times 10^{-5}\)
- C \(3 \cdot 4 \times 10^{-5}\)
- D \(4 \cdot 8 \times 10^{-5}\)
Answer & Solution
Correct Answer
(A) \(5 \cdot 1 \times 10^{-5}\)
Step-by-step Solution
Detailed explanation
\( \chi_1 T_1 = \chi_2 T_2 \) \( 6.8 \times 10^{-5} \times 300 = \chi_2 \times 400 \)
