A) \[\frac{1840}{v}\]
B) \[1840\,v\]
C) \[\frac{v}{1840}\]
D) \[v\]
Correct Answer: C
Solution :
\[{{\lambda }_{e}}=\frac{h}{{{m}_{e}}{{v}_{e}}},{{\lambda }_{m}}=\frac{h}{{{m}_{n}}{{v}_{n}}}\]As\[{{\lambda }_{e}}={{\lambda }_{n}},\] \[\frac{1}{{{m}_{e}}{{v}_{e}}}=\frac{1}{{{m}_{n}}{{v}_{n}}}\]or\[\frac{{{v}_{n}}}{{{v}_{e}}}=\frac{{{m}_{e}}}{{{m}_{n}}}=\frac{1}{1840}\] Or \[{{v}_{n}}=\frac{{{v}_{e}}}{1840}\]
