Physics Elasticity Question 20
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
[MP PET 1985; DPMT 2002]
Options:
A) $ 10\times 10^{12} $
B) $ 100\times 10^{12} $
C) $ 1\times 10^{12} $
D) $ 20\times 10^{12} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ K=\frac{100}{0.01/100}=10^{6}atm=10^{11}\ N/m^{2}=10^{12}\ dyne/cm^{2} $
