Options: \frac{1}{2} {\CV}^2 \frac{3}{4} {\CV}^2 \frac{3}{2} {\CV}^2 2 {\CV}^2 Solution: The two condensers are in parallel. Their equivalent capacitance is
{\C}_{ {\c}}= {\C}+\frac{ {\C}}{2}=\frac{3 {\C}}{2}
The formula for work done is
{\W} =\frac{1}{2} {\C}_{ {\e}} {\V}^2
{\W} =\frac{1}{2} (\frac{3 {\C}}{2}) {\V}^2
{\W} =\frac{3}{4} {\CV}^2" >
