A) \[U/n\]
B) \[nU\]
C) \[{{n}^{2}}U\]
D) \[U/{{n}^{2}}\]
Correct Answer: C
Solution :
\[x'=nx\] \[v=\frac{1}{2}k{{x}^{2}};\,\,\,\,\,\,v=\frac{1}{2}kx'\] \[v'=\frac{1}{2}k\,{{(nx)}^{2}}=\,\,{{n}^{2}}\left( \frac{1}{2}k{{x}^{2}} \right)={{n}^{2}}v;\,\,\,v'={{n}^{2}}v\]You need to login to perform this action.
