What length of the wire of this substance should be suspended verticaly so that the wire breaks under its own weight? (Given: density of material of the wire = 4 × 10^3 kg/m^3 and g = 10 m/s^2 )

The breaking stress for a substance is 10^6 N/m^2. What length of the wire of this substance should be suspended verticaly so that the wire breaks under its own weight? (Given: density of material of the wire = 4 × 10^3 kg/m^3 and g = 10 m/s^2 )

then its new length becomes Young's modulus of rubber is 10^4 N/m^2 and area of cross section is 2 cm^2. If force of 2 x 10^5 dyn is applied along its length
