Q. 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
A) ${10 \times 10}^{12}$
B) ${100 \times 10}^{12}$
C) ${1 \times 10}^{12}$
D) ${20 \times 10}^{12}$
Explanation
(c) $K = \frac{100}{0.01/100} = 10^{6}atm = 10^{11}N/m^{2} = 10^{12}dyne/cm^{2}$
