Tthe Van de Graaff generator and sphere we have been assuming since the start that they are not polarizing each other. This is an approximation. In this question we will start to be able to assess how good this approximation is ? (a) Use the approximation that the Van de Graaff generator and ball are uniformly charged spheres to find the E-field very close to the surface of the Van de Graaff generator, at the point where the +ve x-axis...

PLEASE HELP!
The metal sphere of a small Van de Graaff generator illustrated in the following figure has a radius of 20.0 cm. When the electric field at the surface of the sphere reaches 3.0 x io6 V/m, the air breaks down, and the generator discharges. What is the maximum potential the sphere can have before breakdown occurs?

Lightning can be studied with a Van de Graaff generator, which consists of a spherical dome on which charge is continuously deposited by a moving belt. Charge can be added until the electric field at the surface of the dome becomes equal to the dielectric strength of air. Any more charge leaks off in sparks as shown in the figure below. Assume the dome has a diameter of 38.0 cm and is surrounded by dry ar with a "breakdown. electric...

The sphere of a Van de Graaff generator has a charge of +3.28 μC. A small metal sphere nearby has a charge of +219 nC. They are separated 2.00 m. Let us set axes so that the origin is at the centre of the Van de Graaff generator and the small sphere is at 2.00ˆi m. They are far enough apart that we can make the approximation that they are not polarizing each other, so they can be treated as...
