What is electrostatics?
Electrostatics is a branch of physics that deals with static electricity, which is a non-moving electric charge on the surface of an object.
What happens when an object gains or loses electrons?
A gain of electrons produces negative static charges, while a loss of electrons produces positive charges.
What are the three kinds of subatomic particles in an atom?
The three kinds of subatomic particles are protons, neutrons, and electrons.
What is the charge of protons, electrons, and neutrons?
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral (no charge).
What is the SI unit of electric charge?
The SI unit of electric charge is the coulomb (C).
Describe the basic law of electrostatics.
Like charges repel each other, and unlike charges attract each other.

How can a metal sphere be charged positively by induction? | A metal sphere can be charged positively by induction by bringing a negatively charged object near it, causing electrons to move away from the sphere, and then grounding the sphere to remove excess electrons. |
What is the purpose of a gold leaf electroscope? | A gold leaf electroscope is used to detect the presence of charge, test the quantity of charge, and test the insulation properties of materials. |
What are some dangers associated with electrostatics? | Dangers include sparks and fires, electric shocks, and lightning, which can cause explosions or injury. |
Why is it safer to carry explosive fuels in metal cans instead of plastic cans? | Metal cans allow any generated charges to leak out, preventing the buildup of static electricity that could cause sparks and ignite the fuel. |
