Detailed Solution

$I_{0} = \frac{6}{2} = 3 A$ Just after switch is closed, as both capacitors are uncharged, we have current flow as
Question Image

Long time after switch is closed, both capacitor reach their steady state condition. Now the current flow is

$I_{s} = \frac{6}{2 + 7} = \frac{6}{9} A$
ratio $= \frac{I_{0}}{I_{s}} = 4.5$
