A solid copper cube of 7 cm edge is subjected to a hydraulic pressure of 8000 kPa. The volume contraction of the copper cube is (Bulk modulus of copper =140 GPa )

Question

Accepted Answer

Correct answer: C. (c) Volume of solid copper tube =l^3=7^3 10^-6 m Increase in pressure, p=8000 kPa 8000 10^3 Pa Bulk modulus of copper, =140 Gpa=140 10^9 Pa Bulk modulus B= p ( VV ) ⇒ V= pVB= 8000 10^3 (l )^3140 10^9=19.6 10^-3 cm^3

$A solid copper cube of 7 cm edge is subjected to a hydraulic pressure of 8000 kPa . The volume contraction of the copper cube is (Bulk modulus of copper = 140 GPa)$
