Lightning can be studied with a Van de Graaff generator, which consists of a spherical dome on which charge iscontinuously deposited by a moving belt. Charge can be added until the electric field at the surface of the dome becomesequal to the dielectric strength of air. Any more charge leaks off in sparks as shown in the figure below. Assume the domehas a diameter of 40.0 cm and is surrounded by dry air with a "breakdown" electric field of 3.00 x 10° V/m.(a) What is the maximum potential of the dome?3e5 XYour response differs significantly from the correct answer.

You have built a device that measures the temperature outside and displays it on a dial as a measure of how far away from room temperature outside is. The way the dial works is that a needle with a charged ball on the end is placed between two charged parallel plates.

Given that the charged ball on the needle has a charge of −2.4 µC and the needle can be represented as a string with tension 0.350 N, and is at an angle of 22°, consider the following.

One kind of e-book display consists of millions of very small spheres that float in a thin fluid layer between two conducting, transparent plates. Each sphere is black on one side and white on the other, and possesses an electric dipole moment directed from the white side to the black. When an electric field is applied between the plates, the spheres rotate so that theirdipole moment lines up with the field. Depending on the field’s direction, either the black or the white sides of the spheres can be made visible. The dipole moment of the spheres can be modeled as two opposite charges of magnitude 3.5 × 10-15 C, separated by a distance of 100 mm. What is the maximum possible torque on a sphere if the electric field between the transparent plates is 4.0 × 105 N/C?
