A charge of #-2 C# is at #(6 , -5 )# and a charge of #-3 C# is at #(3, 5 ) #. If both coordinates are in meters, what is the force between the charges?
The distance formula for Cartesian coordinates is
Hence the distance between the two charges is
The electrostatic force between two charges is given by
and its value is
magnitudes of the charges and
Since the force is positive therefore the force is repullsive.
