Electrostatics Flashcards
What are the two subatomic particles in the nucleus of an atom?
Protons and neutrons
Which subatomic particles cannot move or change from the nucleus and atom?
Protons and neutrons
Which subatomic particles move in/from the nucleus and atom?
Electrons
What does “neutral“ mean?
no. of proton = no. of neutrons
What is the Triboelectric effect?
Tribo-electric charging is a type of contact electrification in which certain materials become electrically charged after they come into contact with different materials and are separated (rubbing)
The polarity and strength of the charges produced differ according to the …
materials
All materials contain ….charges (protons) and negative charges (…)
Positive
Electrons
An object has a different/equal number of protons as it does electrons. Therefore the object has/doesn’t have a net charge
Equal
Doesn’t have
Positively charged objects have lost or have had electrons removed therefore they are …. ….
Electron deficient
Negatively charged objects have an excess of electrons therefore they have … ….
Gained electrons
What is the force exerted by non-moving (static) charges on each other called?
The Electrostatic force
What is an electrostatic force?
The force exerted by non-moving (static) charges on each other
The electrostatic force between like charges is …
Repulsive
The electrostatic force between unlike/ opposite charges is …
Attractive
Explain the scenario of a neutral object coming close to a positive object
The neutral object’s electrons will move closer and separate from the protons in the neutral objectE
