A copper wire, $1 m m^{2}$ Area of cross section is just stretched between two fixed points at a temperature of $30^{0} C$ . Determine the tension in the wire when the temperature falls to $20^{0} C$ . (coefficient of linear expansion of tungsten $= 2 \times 10^{- 6} /^{0} C$ ; Young's modulus of tungsten $= 12 \times 10^{10} N m^{- 2}$ )
