SEE if the whole charge is at an equal distance from the point where V is 2 be calculated, then we can write.........
V = k(Qnet)/r.....
in these 2 cases, Qnet = 0.......
so V1 = V2 = 0.....!!!!!

ELECTRIC POTENTIAL IN BOTH THE CASES IS ZERO........

Remember Cedric. Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory.

see, for any general case, Vres = SUM Vi =SUM (Q1+Q2+..Qn)/r =(here) 0 (Q+Q-Q-Q), for both cases
