Two conductive, spherical shells are charged with 25.0 nC and -25.0 nC that spread out uniformly as shown at right. The radius of the inner shell is 3.4 cm and the outer shell is 9.6 cm. The shells are concentric.

ε_o=8.85418782*10^-12 farads/meter

Two conductive, spherical shells are charged equally as shown at right. The radius of the inner shell is 4.6 cm and the outer shell is 9.2 cm. The shells are concentric. The voltage between the shells is measured to be 2198 Volts.

ε_o=8.85418782*10-12 farads/meter

Two conductive, spherical shells are charged equally as shown at right. The radius of the inner shell is 2.0 cm and the outer shell is 8.4 cm. The shells are concentric. The E-field at the midpoint between the 2 shells is 99714 N/C.
