Elastic limit of a particular steel wire is 2.5 xx 10^(10) N//m^(2) maximum strain to which the wire be subjected without losing elasticity is (Y_("steel") = 2 xx 10^(11) N//m^(2))

Young's modulus of brass and steel are 10 xx 10^(10) N//m and 2 xx 10^(11) N//m^(2) , respectively. A brass wire and a steel wire of the same length are extended by 1 mm under the same force. The radii of the brass and steel wires are R_(B) and R_(S) . respectively. Then

If same tensile force is applied on two wires, there will an extension of 1xx10^(-3) m in them. The Young's moduli and radii of these wires are 10xx10^(10)N//m^(2) and 20xx10^(10)N//m^(2) and R_(1) and R_(2) respectively then R_(2) is equal to
