Final Jeopardy
$200 Answer Electrostatics
Conductors have “free” electrons but insulators have tightly bound electrons. This means that conductors allow electrons to move through them easily, insulators do not.
$300 ElectrostaticsWhen charges separate themselves due to charging by polarization, how does this happen?
$500 Electrostatics
What type of charging is occurring in a clothes dryer? Why do we use dryer sheets?
$500 Answer Electrostatics
Friction and conduction.
In the dryer the clothes rub together, transferring electrons. The dryer sheet is used to take away any extra charge.
$100 Question Electric Fields
If you walk into a region of space and suddenly feel a force, the space is said to contain a ____________.
a) Black hole
b) Charged object
c) Force field
d) Heavy object
e) Large charge
$200 Question Electric Fields
If this were a hollow object with a build up of negative charge, draw how the charge would distribute it self inside and explain what you draw.
$300 Question Electric Fields
Draw the electric field lines between a positive and a negative charge.
$400 Question Electric Fields and Potential
Draw a diagram of the electric field lines between two similar positive charges.
$500 Question Electric Fields and Potential
Why are you safe in a lighting stormIf you are sitting in your car?
$500 Answer Electric Fields and Potential
The car acts like a faraday cage. All of the charge gathers on the outside of the car keeping you safe.
$100 Question Coulomb
Which tends to be a stronger force, gravitational force or electrostatic force?
$200 Question Coulomb
If you quadruple the distance between two charges, what happens to the electrostatic force?
$300 Question Coulomb
What will happen to the force between two charges if the distance remains the same, but the amount of charge increases?
$400 Question Coulomb
What is the electrostatic force between two negative charges of 0.098 C separated by a distance of 5 meters? Is it attractive or repulsive?
$500 Question Coulomb
What is the electrostatic force between a proton and an electron separated by a distance of 7 x 10-8 N?
$200 Question Extra
What does the symbol q represent in Coulomb’s Law equation?
What are the units for q?
$200 Question ExtraWhat type of charging causes the plastic on a CD to stick to you when you first unwrap the CD?
$400 Answer Extra
You can charge yourself by friction when you slide in and out and then arc to the gas when you go to take the pump out of the tank. FIRE!
$500 Question ExtraWhy doesn’t it hurt you to have static charge built up on you? What actually hurts you when you get electrocuted?
Final JeopardyA 3kg sphere with a charge of +3 x 10-4 C is placed 0.7m from a 5kg sphere with a charge of +4 x 10-7 C. Calculate all the forces (this means electric force and gravitational force) present and draw a force diagram of the forces. Which force is bigger?
