When a force is applied on a wire of uniform cross-sectional area 3×1

1.	When a force is applied on a wire of uniform cross-sectional area 3×10−6m2and length 4m, the increase in length is 1mm. Energy stored in it will be (Y=2×1011Nm−2)
Answer» When a force is applied on a wire of uniform cross-sectional area $3 \times 10^{- 6} m^{2}$ and length $4 m$ , the increase in length is $1 m m$ . Energy stored in it will be $(Y = 2 \times 10^{11} N m^{- 2})$
