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 $dynes/c{m}^2$ is

• A. $10\times {10}^{12}$
• B. $100\times {10}^{12}$
• C. $1\times {10}^{12}$
• D. $20\times {10}^{12}$

Answer 1

The correct option is C

$1\times {10}^{12}$

$K=\frac{100}{0.01/100}={10}^{6}atm={10}^{11}N/m^2={10}^{12}dyne/c{m}^2$
