A) \[\frac{K}{U}=\frac{{{a}^{2}}-{{x}^{2}}{{\omega }^{2}}}{{{x}^{2}}{{\omega }^{2}}}\]
B) \[\frac{K}{U}=\frac{{{a}^{2}}-{{x}^{2}}}{{{x}^{2}}}\]
C) \[\frac{K}{U}=\frac{{{x}^{2}}}{{{a}^{2}}-{{x}^{2}}}\]
D) \[\frac{K}{U}=\frac{{{x}^{2}}{{\omega }^{2}}}{{{a}^{2}}-{{\omega }^{2}}{{x}^{2}}}\]
Correct Answer: B
Solution :
\[\frac{K}{U}=\frac{\frac{1}{2}m{{\omega }^{2}}({{a}^{2}}-{{\omega }^{2}})}{\frac{1}{2}m{{\omega }^{2}}{{x}^{2}}}\] \[=\frac{{{a}^{2}}-{{x}^{2}}}{{{x}^{2}}}\]You need to login to perform this action.
