Physics · UNITS AND MEASUREMENT
हिन्दीIn 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 \( \text{dyne cm}^{-2} \)?
Correct answer · Option 2
\( 10^6\text{ dyne cm}^{-2} \)
Explanation
Since \( 1\text{ N m}^{-2} = \frac{10^5\text{ dyne}}{10^4\text{ cm}^2} = 10\text{ dyne cm}^{-2} \), we get \( 1\text{ bar} = 10^5 \times 10 = 10^6\text{ dyne cm}^{-2} \).
