A) \[\frac{W}{4}\]
B) \[\frac{W}{2}\]
C) 2 W
D) 4 W
Correct Answer: D
Solution :
From the formula, \[W=\frac{{{Q}^{2}}}{2C}\] ... (i) \[W=\frac{{{(2Q)}^{2}}}{2C}\] \[(\because \,\,\,Q=2Q)\] \[\Rightarrow \] \[W=4\frac{{{Q}^{2}}}{2C}\] \[\Rightarrow \] W = 4 W [From Eq. (i)]You need to login to perform this action.
