Two wires of equal length and cross-sectional area
\( \mathrm{P} \)
are suspended as shown in figure. Their Young's modulli are \( Y_{1}=2 \times 10^{11} \mathrm{~Pa} \) and \( Y_{2}=0.90 \times 10^{11} \mathrm{~Pa} \) respectively. What will be the equivalent Young's modulus of combination?
(1) \( 2.90 \times 10^{11} \mathrm{~Pa} \)
(2) \( 1.45 \times 10^{11} \mathrm{~Pa} \)
(3) \( 1.34 \times 10^{11} \mathrm{~Pa} \)
(4) \( 4.25 \times 10^{11} \mathrm{~Pa} \)
