A) \[\frac{U}{5}\]
B) U
C) 5 U
D) 25 U
Correct Answer: D
Solution :
\[U\propto {{x}^{2}}\] \[\Rightarrow \]\[\frac{{{U}_{2}}}{{{U}_{1}}}={{\left( \frac{{{x}_{2}}}{{{x}_{1}}} \right)}^{2}}={{\left( \frac{0.1}{0.02} \right)}^{2}}=25\]\[\therefore \]\[{{U}_{2}}=25\,U\]You need to login to perform this action.
