00:07

well we've all played around with magnets at some point in our lives

00:27

00:32

negative side of one magnet on the positive side of the other magnet well

00:36

they'll stick together if you try to put the two negative sides together they'll

00:40

push each other back that's because identical charges always repel each [magnets repelling each other]

00:46

other and opposite charges always attract each other so in our case here [magnets attract to each other]

00:50

we've got two negative charges making option B the correct choice those

00:55

particles will repel each other more than a vegan and a butcher at a cookout [two men BBQing]

00:58

options a and C violate basic laws of physics and well that's never gonna work

01:03

an option D well it can be determined so DS out just remember opposite charges

01:09

attract and like charges repel and also remember that Santa looks good for his

01:14

age and we're not just saying that okay [Santa Claus at the North Pole]
