Physics - Static electricity
test questions and answers

What do electrostatic forces do to each other?
two positives will repel each other, as will two
negatives but a negative and a positive will be
attracted
How are electric fields shown?
With arrows pointing inwards or outwards
depending if the particle attracts or repels a
proton
How does the sticky balloon experiment work?
Rubbing the balloon on your shirt transfers
electrons to it which gives the balloon a negative
charge. When placed near the balloon, the free
electrons in the wall are repelled by the balloon
which leaves a positive charge on the wall by the
balloon, making the balloon stick
Why does your hair stand up when you touch a Van
de Graaf generator?
The belt within the Van de Graaf generator strips
electrons from the dome which positively charges
the dome. The electrons in the person then repel
each other as their electric fields interact, causing
them to spread out over all objects in contact,
including the dome. This leaves an overall deficit of
electrons in the person. This causes each strand of
