Given information
Two systems of two isolated charges are given
(1) System of two unlike charges.
(2) System of two like charges.
To find if electrical potential energy is positive or negative and it's significance in all above cases.
Step-by-step explanation
Step 1.
(1). System of two unlike Charges:
- If we consider the zero location for potential energy to be when the charges are infinitely far apart, the electric potential energy of two dissimilar charges is negative.
- When there are charges that are unlike each other, work must be done to separate them.
Let us consider two charges 
the electric potential energy is given by:
where 
is the separation between the charges and 
Coulomb's constant
