Solve it · Build the Solution
Put Coulomb’s law to work: sort what you know, build the solution step by step, then check it against the physics.
SOLVE IT · COULOMB’S LAW AND SUPERPOSITION
Build the solution, then run it.
First sort the knowns and unknowns. Then choose and order the solution blocks. Some cards and blocks contain a common mistake.
Block bank
Quantities for Step 1
Use + Known or + Unknown, or drag a card into a box. Some cards belong in neither box.
Solution blocks for Step 2
🔒 Sort the knowns and unknowns correctly to unlock the solution blocks.
Tap or press Enter on a block to add it to your solution. On a computer you can also drag it.

Unknowns
Step 2 · Solution steps
Put one block per step in a valid order. Use ↑ ↓ to reorder and ✕ to return a block to the bank.

Your answers vs the physics
CHECK| Quantity | Your block | Physics |
|---|
Check your solution to compare its numbers with the physics.
k = 8.988 × 10⁹ N·m²/C² in the engine; the problems quote 8.99 × 10⁹, which agrees to 3 significant figures. Step 1 score = quantities in the right box ÷ quantities needed; Step 2 score = correct blocks in a valid position ÷ required steps. Tries count each check. Nothing is saved or sent; report your score to your instructor if asked.
