Question

The presssure of a medium is changed from `1.01xx10^(5) Pa` to ` 1.165xx10^(5) Pa` and change in volume is `10 % ` keeping temperature constant . The bulk modulus of the medium is
(a) `204.8 xx 10^(5) Pa` (b) `102.4xx10^(5) Pa` (c ) `5.12xx10^(5) Pa`
(d) `1.55xx10^(5) Pa`

Answer 1

Correct Answer - A
From the definition of bulk modulus , ` B = - (Deltap)/((Delta V//V))`
Substituting the values , we have
` B = ((1.165 - 1.01)xx10^(5)) /((10//100)) = 1.55xx10^(5) Pa`
Therfore , the correct option is (d).
