An ideal gas is enclosed in a cylinder at pressure of $\displaystyle 2$ atm and temperature, $\displaystyle 300$ K . The mean time between two successive collisions is $\displaystyle 6 \times 10^{-8} \mathrm{~s}$. If the pressure is doubled and temperature is increased to $\displaystyle 500$ K, the mean time between two successive collisions will be close to :
Official answer
(4)
$\displaystyle 4 \times 10^{-8} \mathrm{~s}$
