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