Physics · UNITS AND MEASUREMENT

In the CGS system, the unit of pressure is \( \text{dyne cm}^{-2} \). Given that \( 1\text{ bar} = 10^5\text{ Pa} \) (where \( 1\text{ Pa} = 1\text{ N m}^{-2} \)), what is the value of \( 1\text{ bar} \) expressed in \( \text{dyne cm}^{-2} \)?

1. A
   \( 10^5\text{ dyne cm}^{-2} \)
2. B
   \( 10^6\text{ dyne cm}^{-2} \)
3. C
   \( 10^7\text{ dyne cm}^{-2} \)
4. D
   \( 10^4\text{ dyne cm}^{-2} \)
