One can determine the charge for an unknown material by using negligible friction. One will then be able to compare reactions between different charges that are brought near the unknown material.

When does the charge exist?
When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.

What is the use of gold leaf electroscope?

What can you determine from an electric field vector at one point?
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
Material through which charge can easily flow?
Conductor.
How do you find charge of an unknown material that either they positively charged or not?
Tie the unknown object and an object with a known charge to separate strings. Hold the two objects up by the strings, and bring them near each other. If the objects repel it means that the unknown object has the same charge as the known object. If they attract it means the unknown object has an opposite charge as the known object.
An unknown material is rubbed with silk and becomes charged Explain how you could use a negative acetate strip or a positive glass rod to determine the type of charge on the unknown material?
If you move the material near the negative acetate strip and they repel each other, the material negatively charged. If they move towards each other, it is positively charged. If you move the material near the positive rod and they attract, the material is negatively charged. If they repel, it is positively charged. This is because opposite charges attract and same charges repel.

What are the factors which determine costs?
The price the store had to pay for the product, which values on the workers at the factory, the material used, and the extra charge the factory owner will charge. Also the importation, and how much the store wants to get extra.
