The two wires shown in figure are made of the same material which has a breaking stress of `8xx10^8Nm^-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=20kg` and the hanger is light. a. 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? b. Repeat the above part `m_1=10 kg and m_2=36kg`.
