1.	A wire of area of cross-section 3.0 mm2 and natural length 50 cm is fixed at one end and a mass of 2.1 kg is hung from the other end. Find the elastic potential energy stored in the wire in steady state. Young’s modulus of the material of the wire =1.9×1011 Nm−2. Take g=10 ms−2.
Answer» A wire of area of cross-section $3.0 m m^{2}$ and natural length $50 c m$ is fixed at one end and a mass of $2.1 k g$ is hung from the other end. Find the elastic potential energy stored in the wire in steady state. Young’s modulus of the material of the wire $= 1.9 \times 10^{11} N m^{- 2}$ . Take $g = 10 m s^{- 2}$ .
