Best Answer

In order to explain this, we should consider its working.

The Van De Graaff Generator has two metal comb one which is held near the end of belt known as emitter comb and another comb which is placed near the upper end of the belt known as collector comb.The emitter comb ,as it is given high positive potential with respect to earth ,the discharge of its action of its pointed ends set up as electric wind of positive charges.These positive charges are sprayed on the belt which carries them to the top .This make the shell of a Van De Graaff Generator positively charge.

But keep this is mind : The charge on the shell depends on the charge on the belt.

What is indoor lightning?

Lightning can reach the interior of a structure in two ways : an ionized airflow or a conducted charge. The airflow occurrence usually requires two open windows or doors, creating a path through which a lightning strike may travel. This is a rare occurrence. More commonly, lightning strikes a metal roof or siding, or directly hits a telephone or electric wire on the exterior. A high voltage discharge flows through interior wiring, reaching persons or machines inside the building. For this reason, traditional wired phones can be more dangerous in a storm than cordless or cellular devices. A controlled form of "lightning" can be created indoors using a Van De Graaff high-voltage charge generator. (see the NOAA and Van De Graaff related links)


What type of attraction exists between the slight positive charge of a hydrogen atom and slight negative charge of a nearby atom?

When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.


Is electricity is natural or man made?

Both. Some kinds are natural and some man-made.


Why vanderwall forces are weak forces?

The question should be, why is there a force at all! In the case of van der Waals forces, a.k.a. "induced dipole - induced dipole", there is no charge separation, or charge, present to begin with; only temporary dipoles caused by random movement of particles.


How is a Van Der Waals force formed?

These bonds have an approximate energy of 0.5-1.0 kcal/mol. see related link

Can van de graaff generator hold any amount of charge?

No, the Van de Graaff generator can produce a large amount of charge but does not hold the charge itself. The generator must be in motion in order to produce electricity. Once the motion stops, the charge is lost.


A pie pan is attached to a negatively charged Van de Graaff generatorThen the pie pan is removed from the areaDescribe the state of charge of the pie pan as this process is performed?

It is a positivly charged pan because the pan is negative in the first place and to negatives are a positive
