Question:

A wire is bent in the form of a regular hexagon and a total charge $q$ is distributed uniformly on it. What is the electric field at the centre? You may answer this part without making any numerical calculations.

Solution:

Regular hexagon is an equipotentential surface Thus charge at every point on surface is same. Therefore, Net electric field at centre is zero.
