A) \[\frac{hv}{4}\]
B) \[\frac{hv}{3}\]
C) \[\frac{hv}{2}\]
D) \[\frac{2hv}{3}\]
Correct Answer: D
Solution :
\[\frac{\frac{1}{2}m{{v}^{2}}}{\frac{1}{2}m{{v}^{2}}}=\frac{hv-\text{o }\!\!|\!\!\text{ }}{h(2v)-\text{o }\!\!|\!\!\text{ }}\] or \[\frac{1}{4}=\frac{hv-\text{o }\!\!|\!\!\text{ }}{2hv-\text{o }\!\!|\!\!\text{ }}\] or \[\text{o }\!\!|\!\!\text{ =}\frac{2hv}{3}\]You need to login to perform this action.
