As we have learnt,

 

Electric Potential energy -

Work done in bringing the given charge from infinity to a point in the electric field.

- wherein

It is denoted by U.

 

 

 

Since we know potential energy  U = k\frac{Q_1 Q_2}{r}
As r increases, U decreases in magnitude. However depending upon the fact whether both charges are similar or disimilar, U may increase or decrease.


Option 1)

May Increase or decrease.

Option 2)

Increases

Option 3)

Decreases

Option 4)

Remain the same.
