Wave Mechanics Question 512
Question: When a pressure of 100 atmosphere is applied on a spherical ball, then its volume reduces to 0.01%. The bulk modulus of the material of the rubber in $ dyne/cm^{2} $ is
Options:
A) $ 10\times 10^{12} $
B) $ 100\times 10^{12} $
C) $ 1\times 10^{12} $
D) $ 10\times 10^{12} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Bulk modulus $ K=\frac{P}{\frac{\Delta V}{V}}=\frac{100}{0.01/100} $
$ =10^{6}atm=10^{11}N/m^{2}=10^{12},dyne/cm^{2} $
