. Assume that 
is the electrical potential at the position of that charge. The electrical potential of that point charge will be equal to:
.
; (that's -8.0 microjoules, which equals to 
)
. 
.
negative charge to the origin will not require any external work. Instead, this process will release 320 μJ of energy. As a result, the electrical potential energy is a negative value.
