A) 5 : 1
B) 25 : 4
C) 20 : 1
D) 8 : 4
Correct Answer: B
Solution :
[B] \[\frac{{{\lambda }_{B}}}{{{\lambda }_{A}}}=\sqrt{\frac{{{m}_{A}}{{E}_{A}}}{{{m}_{B}}{{E}_{B}}}}\] \[\frac{{{E}_{A}}}{{{E}_{A}}}={{\left( \frac{{{\lambda }_{B}}}{{{\lambda }_{A}}} \right)}^{2}}.\frac{{{m}_{B}}}{{{m}_{A}}}\]\[={{\left( \frac{5}{2} \right)}^{2}}.\frac{1}{2}=\frac{25}{4}\]You need to login to perform this action.
