# A $4 \mu F$ capacitor is charged by a $200\; V$ supply. It is then disconnected from the supply, and is connected to another uncharged $2 \mu F$ capacitor. How much electrostatic energy of the first capacitor is lost in the form of heat and electromagnetic radiation?
$\begin{array}{1 1} 2.7 \times 10^{-2}\;J \\2.67 \times 10^{-2}\;J \\ 17 \times 10^{-2}\;J \\ 2.5 \times 10^{-2}\;J \end{array}$
