A charge of #2 C# is at #(-2 , 4 )# and a charge of #-1 C# is at #(7 , 3 ) #. If both coordinates are in meters, what is the force between the charges?
First we find the distance between the 2 charges by using the normal Euclidean metric distance formula in
Now we may apply Coulomb's Law in electrostatics to find the magnitude of the electrostatic force between these 2 charges as follows :
Since the 2 charges are opposites, they attract each other.
