    A sphere of radius 3 cm is subjected to a pressure of 100 an n. Its volume decreases by 0.3 cc. What will be its bulk modulus?

    A)  \[4\pi \times {{10}^{5}}\] atm    

    B)  \[4\pi \times {{103}^{4}}\] atm

    C)  \[4\pi \times {{10}^{6}}\]atm    

    D)  \[4\pi \times {{10}^{8}}\]

    E) None of these

    Correct Answer: E

    Solution :

    Given, \[r=3\,cm,\,\,\Delta V=0.3\,cc\] Bulk modulus \[K=-\frac{pV}{\Delta V}\] \[=\frac{100\times \frac{4}{3}\pi {{r}^{3}}}{0.3}\] \[=4\pi \times 3\times {{10}^{3}}atm\] We can see there is no correct choice given.
