It was formulated by Charles-Augustin de Coulomb in the 18th century and remains a cornerstone in the study of electrostatics. What Is Coulomb's Law? Coulomb's Law states that: > The electrostatic force \( F \) between two point charges \( q_1 \) and \( q_2 \) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance \( r \) between them. Mathematically, this is expressed as: \[ F = k \frac{|q_1 q_2|}{r^2} \] where: - \( F \) is the magnitude of the electrostatic force between the charges - \( q_1 \) and \( q_2 \) are the magnitudes of the charges - \( r \) is the distance between the charges - \( k \) is Coulomb's constant, approximately \( 8.9875 \times 10^9 \, \text{Nm}^2/\text{C}^2 \) Key Points about Coulomb's Law: - The force is attractive if the charges are of opposite signs and repulsive if of the same sign. - The law applies to point charges or spherically symmetric charge distributions. - The magnitude of the force depends on both the size of the charges and their separation distance. --- Features of Coulomb's Law Practice Worksheet 152 Coulomb's Law Practice Worksheet 152 is tailored to assist students in applying theoretical knowledge to practical problems.
