Answer 1

1.610^-19 C
9.1110^ -31kg

Question 2

Electrostatic force between 2 point charge obey

Answer 2

Newton’s third law
The force on one charge is the action and on the other is reaction and vice versa

Question 3

Is the rate at which charges flow past a point on a circuit

Answer 3

Current
I=q/t

Question 4

Current of 1 ampere means that there is

Answer 4

1 coulomb of charge passing through a cross section of a wire every one second
1A=1C/1s=1Cs^-1

Question 5
