A) \[\frac{\pm A}{\sqrt{3}}\]
B) \[\frac{\pm A}{\sqrt{2}}\]
C) \[\frac{\pm A}{3}\]
D) \[\frac{\pm A}{2}\]
Correct Answer: B
Solution :
Energy of oscillation \[E=\alpha {{A}^{4}}\] KE of mass \[K=E-U=\alpha ({{A}^{4}}-{{x}^{4}})\] \[\Rightarrow \,K=-3U\] \[\Rightarrow \,\alpha =({{A}^{4}}-{{x}^{4}})=3a{{x}^{4}}\Rightarrow \,\frac{\pm \,A}{\sqrt{2}}\]You need to login to perform this action.
