Figure
How much work would be required to remove a metal sheet of thickness \(l\) from between the plates of a capacitor (see the figure), assuming the battery
remains connected so the voltage remains constant?(Figure 1)
Express your answer in terms of the variables \(A\), \(V\), \(l\), \(d\), and appropriate constants.
\(W = \frac{1}{2} \frac{\epsilon_0 A V^2}{d - l}\)

How much work would be required to remove a metal sheet of thickness \(l\) from between the plates of a capacitor, assuming the battery is disconnected
so the charge remains constant?
Express your answer in terms of the variables \(A\), \(V_0\), \(l\), \(d\), and appropriate constants.
\(W = \)
