A) \[\frac{U}{n}\]
B) \[nU\]
C) \[{{n}^{2}}U\]
D) \[\frac{U}{{{n}^{2}}}\]
Correct Answer: C
Solution :
Potential energy of the spring \[U=\frac{1}{2}k\,{{x}^{2}}\] ?(i) and \[U=\frac{1}{2}k{{(nx)}^{2}}\] \[\Rightarrow \] \[U={{n}^{2}}\frac{1}{2}k\,{{x}^{2}}\] \[\therefore \] \[U={{n}^{2}}U\] [From Eq. (i)]You need to login to perform this action.
