1.	One end of steel wire is fixed to ceiling of an elevator moving up with an acceleration of 2 m/s2 and a load of 10 kg hangs from the other end. Area of cross - section of the wire is 2 cm2. The longitudinal strain in the wire is[ Y=2×1011 N/m2 ]
Answer» One end of steel wire is fixed to ceiling of an elevator moving up with an acceleration of $2 {m/s}^{2}$ and a load of $10 kg$ hangs from the other end. Area of cross - section of the wire is $2 {cm}^{2}$ . The longitudinal strain in the wire is $[Y = 2 \times 10^{11} {N/m}^{2}]$
