Correct option is D)

 

 Let distance between and be .

Find potential difference of both

Let distance between and be

Then potential at any distance from point is given by

NoW

 Differentiating between both potential energy

therefore for

therefore potential decreases and for

therefore potential increases
 Hence first decreases then increases option (D)
