The figure shows a parallel-plate capacitor of plate area A and plate separation d. A potential differenceV0 is applied between the plates.
The figure shows a parallel-plate capacitor of plate area A and plate separation d. A potential differenceV0 is applied between the plates. While the
battery remains connected, a dielectric slab of thickness b and dielectric constant κ is placed between the plates
as shown. Assume A = 130 cm2, d = 1.94

Figure a shows three plastic sheets that are large, parallel,
and uniformly charged. Figure b gives the component of the net
electric field along an x axis through the sheets. The scale of the
vertical axis is set by Es = 5 × 105 N/C. What is the ratio of the
charge density on sheet 3 to that on sheet 2?

(Figure 1) Consider three plastic balls (A, B, and C), each
carrying a uniformly distributed charge equal to either +Q, -Q or
zero, and an uncharged (neutral) copper ball (D). A positive test
charge (T) experiences the forces shown in the figure when brought
very near to the individual balls. The test charge T is strongly
attracted to A, strongly repelled from B, weakly attracted to C,
and strongly attracted to D.
