A metal block is experiencing an atmospheric pressure of `1 xx 10^(5)N//m^(2)`, when the same block is placed vacuum chamber, the freactional change in its volume is (the bulk modulus of metal is `1.25 xx 10^(11) N//m^(2)`)

Options

A. `4xx10^(-7)`
B. `2xx10^(-7)`
C. `8xx10^(-7)`
D. `1xx10^(-7)`

Answer

C

Explanation

(c) As B`=(-Deltap)/(DeltaV//V)`
`therefore (DeltaV)/(V)=(Deltap)/(B)=(10^(5))/(1.25xx10^(11))=8xx10^(-7)`
