Capacitance of Parallel Plate Capacitor

Two gases N...

Question

Two gases $N O$ and $O_{2}$ were introduced at the two ends of a one meter long tube simultaneously (tube of uniform cross-section). At what distance from $N O$ gas end, Brown fumes will be seen. (write the value to the nearest integer)

Open in App

Solution

As we know,
$\frac{d_{N O}}{100 - d_{N O}} = \sqrt{\frac{32}{30}} \Rightarrow d_{N O} = 50.8 c m$
