Answer 1

Neutrons and protons

Question 2

Charge of proton

Answer 2

Positive

Question 3

Charge of neutron

Answer 3

Nothing

Question 4

Charge of electron

Answer 4

Negative

Question 5

What happens if electrons leave atoms

Answer 5

Positive ion formed

Question 6

What happens if electrons are added to atoms

Answer 6

Negative charge

Question 7

How does something become charged by friction

Answer 7

When you rub an insulator with another insulator, electrons are transferred from one to the other so one becomes positively charged and one becomes negatively charged

Question 8

Do charged objects exert a contact or non - contact force on each other

Answer 8

Non - contact (force of attraction)

Question 9

Why do charged objects exert forces on each other

Answer 9

First object creates an electrical field around itself and the second object feels a force because of this field

Question 10

Which way do arrows go on a force diagram

Answer 10

Point in direction positive charge would go
