1.	A wire of area of cross section 3.0 mm2and 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 = 1.9×1011Nm−2.Takeg=10ms−2
Answer» A wire of area of cross section 3.0 $m m^{2}$ 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 = $1.9 \times 10^{11} N m^{- 2} . T a k e g = 10 m s^{- 2}$
