The correct option is B 1.08×10−6 m3
From the data given in the question,
Change in pressure (ΔP)=106 Nm−2−105 Nm−2=9×105 Nm−2
Initial volume V=2×10−3 m3
We know that,
Compressibility =1|Bulk modulus|
From the definition of Bulk modulus of elasticity,
Bulk modulus (B)=−V×ΔPΔV
⇒ Compressibility =(ΔVV)ΔP
⇒60×10−11=ΔV2×10−3×9×105
⇒ΔV=60×10−11×2×10−3×9×105
⇒ΔV=1.08×10−6 m3
Hence, option (b) is the correct answer.
