Properties of Matter question

2025 · 2 Apr · Shift 1 · Q71

JEE MainPhysicsProperties of MatterNumerical+4 / −1
A steel wire of length 2 m and Young's modulus 2.0×1011 N m−22.0 \times 10^{11} \mathrm{~N} \mathrm{~m}^{-2}2.0×1011 N m−2 is stretched by a force. If Poisson ratio and transverse strain for the wire are 0.2 and 10−310^{-3}10−3 respectively, then the elastic potential energy density of the wire is ‾\underline{\hspace{2cm}}​×105\times 10^5×105 (in SI units).
