A) \[\frac{\theta }{2}\]
B) \[\frac{\theta }{\sqrt{2}}\]
C) \[\frac{\theta }{\sqrt{3}}\]
D) \[\frac{\theta }{3}\]
Correct Answer: B
Solution :
Maximum energy stored in the capacitor \[{{U}_{\max }}=\frac{{{Q}^{2}}}{2C}\] The energy is stored equally in electric and magnetic fields. So, Energy is eleactric field \[E=\frac{1}{2}\left( \frac{{{Q}^{2}}}{2C} \right)\] Now \[\frac{{{Q}^{2}}}{2C}=\frac{1}{2}\frac{{{Q}^{2}}}{2C}\] \[\therefore \] \[Q'=\frac{Q}{\sqrt{2}}\]You need to login to perform this action.
