Chapter 25, Problem 32P

(a)

To determine

To show: The sheet creates uniform electric field at nearby points with magnitude $E=\frac{Q}{2A\epsilon }$.

(b)

To determine

To show: The sheet creates uniform electric field in the space between them with magnitude $E=\frac{Q}{A\epsilon }$.

(c)

To determine

To show: The positive plate at potential $\frac{Qd}{\epsilon A}$.

(d)

To determine

To show: The capacitance of the pair of the plate is $C=\frac{A\epsilon }{d}=\frac{kA{\epsilon }_0}{d}$.
