Answer to Question #299803 in Physics for Joie

Question

3. If there were twice as much as charge on one of the charged objects near the charge sphere, would the electric potential energy of the object in the field of the charged sphere be the same or would it be twice s great? Would the electric potential of the object be the same or would it be twice as great?

Answer 1

The electric potential energy of charge in exernal field

$$W=qV$$

Hence, for the charge with doubled charge the energy would be wtice greater. The electric potential of object would be the same.
