The magnetic moment produced in a substance of mass 5 gram is \(6 \times 10^{-7} \mathrm{Am}^{2}\). If its density is \(5 \mathrm{~g} / \mathrm{cm}^{3}\), then intensity of magnetization in \(\frac{\mathrm{A}}{\mathrm{m}}\) will be
- A 6
- B 60
- C \(\frac{1}{6}\)
- D \(0 \cdot 6\)
Answer & Solution
Correct Answer
(D) \(0 \cdot 6\)
Step-by-step Solution
Detailed explanation
volumev \(=\frac{\text { mass }}{\text { density }}=\frac{5_{\mathrm{g}}}{5_{\mathrm{g}} / \mathrm{cm}^{3}}=1 \mathrm{~cm}^{3}=10^{-6} \mathrm{~m}\)
\(=\frac{6 \times 10^{-7}}{10^{-6}}\)
\(=0.6_{\mathrm{Nm}}^{\text {volume }}\)
\(=\frac{6 \times 10^{-7}}{10^{-6}}\)
\(=0.6_{\mathrm{Nm}}^{\text {volume }}\)
