# What is the force, in terms of Coulomb's constant, between two electrical charges of 12 C and -14 C that are 15 m  apart?

$- \text{56k"/75\ "newtons}$

#### Explanation:

According to Coulomb’s law, force between two charged particles is

$\text{F" = ("k q"_1 "q"_2)/("d"^2) color(white)(...)"(where k is Coulomb’s constant)}$

$\text{F" = ("k" × 12 × (-14))/(15^2) = -"56k"/75\ "newtons}$
