Coulomb's law, a Rare card
Coulomb's inverse-square law, or simply Coulomb's law, is a scientific law of physics that describes the amount of force between two electrically charged particles at rest.

Coulomb's law quiz: 3 questions
Three questions on the Coulomb's law card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
This electric force is conventionally called the ______ force or Coulomb force.
Answer
electrostatic. This electric force is conventionally called the electrostatic force or Coulomb force. From the Coulomb's law article on Wikipedia.
In which decade?
Although the law was known earlier, it was first published in ____ by French physicist Charles-Augustin de Coulomb.
Answer
1780s. Although the law was known earlier, it was first published in 1785 by French physicist Charles-Augustin de Coulomb. From the Coulomb's law article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Spanish literature. Spanish literature 79 · Coulomb's law 75 · Surface acoustic wave 72 · Atmospheric chemistry 69 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- This electric force is conventionally called the electrostatic force or Coulomb force.
- Although the law was known earlier, it was first published in 1785 by French physicist Charles-Augustin de Coulomb.
- Coulomb's law was essential to the development of the theory of electromagnetism and may even be its starting point, as it allowed meaningful discussions of the amount of electric charge in a particle.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Coulomb's law article was read about 280,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 62: each hit it takes is cut by 25 %.
How to get Coulomb's law
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
