Solution

Answer:- Zero (0)

Since, all charges are equal in magnitude and equidistant from point O. Then magnitude of electric field intensity will equal.

As Electric field intensity is vector quantity. So direction of vectors of all three will be 120 degree apart from each other.

So, by adding these three vectors we will get zero.
