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...
Please help . Consider a Van de Graaff generator used to accelerate deuterons. The high voltage terminal is charged using an insulating belt that is 25 cm wide and travels at 25 m/s. Charge is sprayed onto the belt by the roller at the low voltage end and removed from the belt inside the high voltage terminal. The belt is given sufficient surface charge density at the low voltage end near the roller to induce an electric field of 1.0...

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?
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...
Suppose a van de Graaff generator has a hollow sphere on top with a raius of 10 cm. (0.1m) and it carries a charge of -1.60 uC or -1.60 x 10^-6 C. A.)How many extra electrons is the ball carrying? B.) What is the value and the direction of the electric field, E, on the surface of the sphere? C.) What is the electric field, E, anywhere inside the sphere? Thank you very much for your answer.
A Van de Graaff generator causes a total charge q to build up on a metal sphere of radius r. Which variable does not affect the electric field at a distance R from the center of the metal sphere? Assume R > r. (1 point) the distance R from the center of the metal sphere the magnitude of the charge q the radius r of the metal sphere the sign of the charge q
An uncharged spherical conductor has a radius of 2.4 m. What is the maximum charge you can deposit on the sphere before dielectric breakdown of the air around it occurs? -> determine the strength of the electric field at the surface of the conductor and compare it against the field strength of 3 × 106 V/m above which air becomes a conductor
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...
