A $2.00 \mathrm{~m}$ brass rod with a $1.00 \mathrm{~mm}$ diameter behaves like a spring under stretching or compression. If the elastic modulus of brass is $9.10 \times 10^{10}\mathrm{~N} / \mathrm{m}^{2}$, then the spring constant of the rod is
A) $4.67 \times 10^{4} \mathrm{~N} / \mathrm{m}$.
B) $2.13 \times 10^{4} \mathrm{~N} / \mathrm{m}$.
C) $4.22 \times 10^{4} \mathrm{~N} / \mathrm{m}$.
D) $3.57 \times 10^{4} \mathrm{~N} / \mathrm{m}$.
E) $2.47 \times 10^{4} \mathrm{~N} / \mathrm{m}$.
