Chapter 24, Problem 92P

(a)

To determine

To Explain: The electric field must have the same value inside the dielectric as in the free space between the plates.

(b)

To determine

To Show: ${\sigma }_1=\text{ 2}{\sigma }_2$

(c)

To determine

To Show:The final capacitance is 1.50 times the capacitance when the capacitor is filled with air.

(d)

To determine

To Show:The final potential difference is $\frac{\text{2}}{\text{3}}\text{V}$ .

(e)

To determine

To Show:The energy stored after the slab is inserted is only two-thirds of the energy stored before insertion.
