May the electric force be with you!
I've got a fielding ...
You Seniors! You are wasting your electric potential!

If the distance between two charges is doubled, what happens to the magnitude of the electric force between two charges? A. Doubles B. Quadruples C. Halves D. Quarters
What is D?

Draw two electric fields, one for +Q and one for -Q.
What is ... look at the drawing!

What is the electric potential energy of a proton and an electron that are 1x10^-10 m apart?
What is -2.3 e-18 J?
200
How many electrons make 1 C of charge?
What is 6.25e18, or 6.25x10^25 electrons?
200
What are the units for electric field?
What is N/C
200
What is the difference between electric potential (Voltage) and electric potential energy (Joules). Why is there a difference between the two?
What is Voltage is potential energy/unit of charge?

Suppose that you have 3 protons all in a row, each 0.05 m apart. What is the net force on the middle proton?
What is 0 N?

Suppose that you have a triangle of -2 microcoulomb charges. Each charge is 1 cm away from the center of a circle. What is the electric field at the center of the charges?
What is 4.32e-14 N/C?

Given a postive charge of 3 mC, what is the electric potential 2 m away from the charge? Bonus: Can you draw a picture of a point that would have the same electric potential?
What is 1.35 e7 V or J/C? Yes, draw a circle and any point on the circle is the same distance from the center charge and thus has the same voltage
