electric field at the center of iquilateral triangle

ITS GONNA ZERO............  BECAUSE IF YOU JOIN THE VERTICES WITH CENTRE THEN THE LINE  MAKES EACH OTHER AN ANGLE 120............  OR YOU GONNA KNOW THAT IF TWO SAME VECTORS INCLINED AT AN ANGLE 120 THEN RESULTANT VECTOR WILL BE SAME AS TWO VECTORS.........  SO RESULTANT VECTOR AND THIRD LINE OPPOSE EACH OTHER AND ELECTRIC FIELD BECOME ZERO...................

 APPOVE MY ANSWER................

Dear Sathish, 

If the charge distribution is symmetric about the center, the electric field at that point is zero.
