A wire suspended vertically from one of its ends is stretched by attaching a weight of \( 200 N \) to the lower end. The weight stretches the wire by \( 1 \mathrm{~mm} \). Then the elastic energy stored in the wire is
[AIEEE 2003]
(a) \( 0.1 \mathrm{~J} \)
(b) \( 0.2 \mathrm{~J} \)
(c) \( 10 \mathrm{~J} \)
(d) \( 20 \mathrm{~J} \)
