Physics - energy
« on: August 04, 2021, 06:53:53 PM »
When an object with an electric charge of 0.220 mC is 68.0 m away from an object with an electric charge of −0.890 mC, the electric potential energy is measured to be  −25.88 J.
Calculate the electric potential energy of this system when the objects are 34.0 m apart.

What equations do you know that may help? Is there one linking separation, charge and energy?
