Answer 1

Medium that allows electric charge to flow easily through it

Question 2

Insulator

Answer 2

Medium that does now allow electric charge to flow easily through it

Question 3

Coulombs law

Answer 3

Force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
