Electrical charges and fields

Question 1

when you rub the insulator, electrons are transferred from

Answer 1

one material to another

Question 2

rubbing a polythene rod with a dry cloth transfers electrons where

Answer 2

to the surface of the atoms of the rod for the cloth

Question 3

rubbing a perspex rod with a dry cloth transfers electrons from where

Answer 3

the surface atoms of the rod on to the cloth

Question 4

its positive charge is equal to what

Answer 4

the negative charge

Question 5

two charged object exert what and why

Answer 5

a non contact force because of their charge

Question 6

whats a non contact force

Answer 6

(a force that acts on an object without requiring physical contact between the objects involved)

Question 7

why do both charged objects exert a non contact force

Answer 7

because of the electrical field

Question 8

the field and therefore the force between the two charged objects becomes what

Answer 8

stronger as the distance between the object decreases
