Two wires shown in figure are made of the same material which has a breaking stress of `8xx10^(8) N/m^(2)`. The area of cross- section of the upper wire is `0.006 cm^(2)` and that of the lower wire is `0.003 cm^(2)`. The mass `m_(1) = 10 kg, m_(2) = 20 kg ` and the hanger is light . Find the maximum load that can be put on the hanger without breaking a wire. Which wire will break first if the load is increased ? ( Take `g = 10 m//s^(2))`
