What is the force, in terms of Coulomb's constant, between two electrical charges of #-45 C# and #30 C# that are #15 m # apart?
You would use Coulomb's Law for this question:
where q1 represents the quantity of charge on object 1 (in Coulombs), q2 represents the quantity of charge on object 2 (in Coulombs), and r represents the distance of separation between the two objects (in meters). "k" is a constant, and it's value is
If we plug in the values we get:
In terms of "k", this would simplify to:
If we sub in the value for k, we get:
A negative force indicates a force of ATTRACTION, whereas a positive force indicates a force of REPULSION.
