along line y=x
						

							
approve if correct n want explination
 
						

							
ok i am  SORRY it was a very bad guss so sorry
ya the ans is y axis 
u need to use the formula 
tan(alpha) =(1/2)tan(teta)
to solve this problem i am sorry i cant explain u with a digram hear but i will try my  level best 
 
here teta=angle made by position vector of the given point with x axis in anticlockwise sence
and alpha= angle made by the Enet with p.v of given point in the same sence
so here tan(teta)=root2
so from above formula we get tan(alpha)=1/(root2)
now draw the digram carefully u see that Enet is along y axis
I AM SURE THIS SOLUTION IS CORRECT
SORRY FOR WRONG ANS BEFORE
I AM NT TRYING TO DO ANYTHING  CALLED “JUGGAD”(maniplation)  OVER HERE 
plz approve if agreed OR IN CASE OF ANY DOUBT ASK IN ANS BOX
i still feeling guilty plz reply
						

							
here alpha is the angle made by the electric field at point P with the position vector of point p
havent u come across this formula  before......????
if no plz learn how to find the electric field at a point in space wh makes an angle (teta) with the dipole 
it is important for jee  if u dont find it in the books u have google it
(it is given in H.C verma,DC PANDAY,cengage)
in books u can find in with digrams so u can undustand better 
PLZ APPROVE if undustood n in case of any doubts ask in ans bos
