Can the belt of a Van de Graaff accelerator be a conductor? Explain.

Short Answer

Expert verified

No, conductor cannot be used for the construction of belt of Van de Graff generator.

Step by step solution

01

Van de Graaff accelerator

Van de Graaf accelerator or generator is an electrostatic generator that produces hundreds of thousands of volts (DC) at low current levels. It uses a moving belt to accumulate electric charge on a hollow metal dome.

02

Using conductor as a belt of Van de Graaff accelerator

If the belt of the Van de Graaff accelerator is made using a conductor, then all the charges sprayed on the belt will immediately flow to the ground. Hence the charge will not be built on the terminal and it will not give rise to high potential.

Hence, the belt of a Van de Graaff accelerator cannot be a conductor.

Bare free charges do not remain stationary when close together. To illustrate this, calculate the acceleration of two isolated protons separated by\({\bf{2}}.{\bf{00}}{\rm{ }}{\bf{nm}}\)(a typical distance between gas atoms). Explicitly show how you follow the steps in the Problem-Solving Strategy for electrostatics.

Considering Figure, suppose that qa=qd and qb=qc . First show that q is in static equilibrium. (You may neglect the gravitational force.) Then discuss whether the equilibrium is stable or unstable, noting that this may depend on the signs of the charges and the direction of displacement of qfrom the center of the square.

Sketch the electric field between the two conducting plates shown in Figure 18.50, given the top plate is positive and an equal amount of negative charge is on the bottom plate. Be certain to indicate the distribution of charge on the plates.

Figure 18.50

(a) Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force can be great enough to support the top piece鈥檚 weight. Assuming equal point charges (only an approximation), calculate the magnitude of the charge if electrostatic force is great enough to support the weight of a\[{\bf{10}}.{\bf{0}}{\rm{ mg}}\]piece of tape held\[{\bf{1}}.0{\bf{0}}{\rm{ cm}}\]above another. (b) Discuss whether the magnitude of this charge is consistent with what is typical of static electricity.

Sketch the electric field lines in the vicinity of the conductor in Figure given the field was originally uniform and parallel to the object鈥檚 long axis. Is the resulting field small near the long side of the object?
