Electrostatics

Question 1

Neutral

Answer 1

Same no. Of protons and electrons

Question 2

Positively charged

Answer 2

Electrons lost

Question 3

Negatively charged

Answer 3

Electrons gained

Question 4

Insulator

Answer 4

Substance that does not allow the flow of charge to go through it

Question 5

Conductor

Answer 5

Substance that does allow the flow of charge through it

Question 6

Triboeletric series

Answer 6

Tells us what charge materials are likely to become

Question 7

Materials more like plastic?

Answer 7

Become negatively charged ( gain electron )

Question 8

Materials more like cloth tend to ?

Answer 8

become positivity charged ( lose electron )

Question 9

Polarsation

Answer 9

Takes place when an uncharged object becomes attracted to a charged object.
Uncharged object is induced wth a charge

Question 10

Electrostatic forces

Answer 10

Forces between charges
When friction takes place one item becomes positively charged and one becomes negatively

Question 11

Two factors that that affect electrostatic force between 2 objects

Answer 11

1) magnitude of charges - greater charge = greater electrostatic
2) distance between charges - greater distance = smaller electrostatic force

Question 12

Law of conservation of charge

Answer 12

Net charge of an isolated system remains constant during any physical process

Question 13

Quantisation of charge

Answer 13

Any charge in the universe consist of an interger multiple of the charge of the electron

Question 14

Columb

Answer 14

Packet of electrons
