5 Questions
According to Coulomb's Law, the force between two point charges at rest is directly proportional to which of the following?
Product of the magnitude of the charges
What happens to the force between two charges if they are unlike (one positive and one negative)?
It becomes attractive
What happens to the force between two charges if they are similar (both positive or both negative)?
It becomes repulsive
What is the expression for the force between two charges placed in a medium?
$F = \frac{q_1 q_2}{4\pi\varepsilon_0 r_{med}^2}$
What does the constant of proportionality K depend on in Coulomb's Law?
Units in which force, charges, and distance are expressed, and properties of the medium
