What is the law that describes the interaction between two electric point charges of the same or different sign?
I - The Coulomb's Law describes the interaction between two electric point charges of the same or different sign.
II - The Coulomb's Law states that the force between two charges is repulsive if they are of the same sign and attractive if they are of different signs.
III - The Coulomb's Law states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) I, II, and III are correct.

A alternativa correta é a letra e) I, II e III estão corretas. A Lei de Coulomb descreve a interação entre duas cargas elétricas pontuais de mesmo ou diferente sinal. Ela estabelece que a força entre duas cargas é diretamente proporcional ao produto das cargas e inversamente proporcional ao quadrado da distância entre elas. Além disso, a lei afirma que a força é repulsiva se as cargas tiverem o mesmo sinal e atrativa se tiverem sinais opostos.
