1
Geoff slides across a car seat and ends up negatively charged. The seat has what charge?
Negative
Positive
It depends on how many electrons Geoff picked up
Neutral
2
Electrostatics is the study of electrons that are static, meaning they...
Move faster than light
Reduce into their constituent elements
Do not move
Move in tight circles in the absence of an applied force
3
What is the charge on an electron?
It depends on what direction it spins
Positive
Negative
Neutral
4
Why is it dangerous to shower in a thunderstorm?
A loud clap of thunder can shatter glass shower doors
You're more likely to be struck by lightning if you are wet
Electrically charged water disassociates into explosive gas
Lightning can travel through pipes
5
Why is it safe to be in a car during a thunderstorm?
The electricity travels around the outside of the metal car
The car's battery generates an opposite charge
The rubber tires keep the car insulated
Cars are low to the ground and aren't usually struck
6
What happens to the electrical force between electrons if the distance between them triples?
1/9 the force
3x the force
9x the force
1/3 the force

Much weaker
Slightly weaker
Slightly stronger
Much stronger
8
What does it mean if the electrical force between two particles is negative?
The particles have opposite charges
The particles have different magnitudes
The force points away from both particles
The particles repel each other
