Question
For a gas sample with N0 number of molecules, function N(V) is given by : N(V) = 
for 0 < V < V0 and N(V) = 0 for V > V0. Where dN is number of molecules in speed range V to V+ dV. The rms speed of the molecules is :
for 0 < V < V0 and N(V) = 0 for V > V0. Where dN is number of molecules in speed range V to V+ dV. The rms speed of the molecules is :Options
A.
B.
C.√2V0
D.√3V0
Solution
Vrms2 = < V2 > = 
=
here 
= N(V)
Vrms2 =
V2 dV = 
V2dV = 
V02 ⇒ Vrms 
.V0.
=
here = N(V) Vrms2 =
V2 dV = V2dV = V02 ⇒ Vrms .V0.Create a free account to view solution
