Electrostatics

Question 1

Principle of conversation of charge

Answer 1

The net charge of an isolated system remains constant during a physical process

Question 2

Conductors

Answer 2

Allow electrons to flow freely through them

Question 3

Insulators

Answer 3

Do not allow the electrons to move through them

Question 4

Elementary charge

Answer 4

The amount of charge carried by one electron. e = -1,6x10^-19

Question 5

Micro coulombs

Answer 5

1 ùC = 1 x 10^-6

Question 6

Nanocoulombs

Answer 6

1 nC = 1 x 10^-9

Question 7

Polarization

Answer 7

A positive rod is brought close to a neutral insulator it will attract the bound electrons to move to the side closer to the rod and cause a positive nuclei to move slightly toward the side of the atoms
