Part 1 - Simple Charges
For each situation below, make a model including: word description, system schema,
energy bar charts, equations and assumptions.
1. A +2 µC charge is 0.03 m away from a +5 µC charge.
2. A -3 µC charge is 0.10 m away from a -8 µC charge.
3. A +2 µC charge is 0.05 m away from a -4 µC charge.
4. A +10 µC charge is infinitely far away a -10 µC charge.
Part 2 - Multiple Charges
For each situation below, make a system schema, energy bar charts, and describe the
motion of the free charges. Write an expression in symbolic form for the total
energy of the whole system of charges.
