A wire of length 0.5 m and area of cross-section m at a temperature of 100°C is suspended vertically by fixing its upper end to the ceiling. The wire is then cooled to 0°C, but is prevented from contracting, by attaching a mass at the lower end. If the mass of the wire is negligible, then the value of the mass attached to the wire is [Young's modulus of material of the wire = N/m ; coefficient of linear expansion of the material of the wire = K and acceleration due to gravity = 10 m/s ]
