The molecules of a given mass of a gas have r.m.s. velocity of \(200\ ms^{-1}\) at \(27^\circ C\) and \(1.0\times10^{5}\ Nm^{-2}\) pressure. When the temperature and pressure of the gas are respectively, \(127^\circ C\) and \(0.05\times10^{5}\ Nm^{-2}\), the r.m.s. velocity of its molecules in \(ms^{-1}\) is :
1. \(100\sqrt{2}\)
2. \(\frac{400}{\sqrt{3}}\)
3. \(\frac{100\sqrt{2}}{3}\)
4. \(\frac{100}{3}\)
