The density of a gas is \[6\times {{10}^{-2}}kg/{{m}^{3}}\] and the root mean square velocity of the gas molecules is 500 m/s. The pressure exerted by the gas on the walls of the vessel is

• A. \[5\times {{10}^{3}}N/{{m}^{2}}\]
• B. \[1.1\times {{10}^{-4}}N/{{m}^{2}}\]
• C. \[0.83\times {{10}^{-4}}N/{{m}^{2}}~\]
• D. \[30N/{{m}^{2}}\]
