MCQ
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 $dyne/c{m^2}$ is
  • A
    $10 \times {10^{12}}$
  • B
    $100 \times {10^{12}}$
  • ✓
    $1 \times {10^{12}}$
  • D
    $20 \times {10^{12}}$
✓

Answer

Correct option: C.
$1 \times {10^{12}}$
c
(c) $K = \frac{{100}}{{0.01/100}} = {10^6}atm = {10^{11}}\;N/{m^2} = {10^{12}}\;dyne/c{m^2}$
