Six point charges equally spaced apart on a circle of radius R , with alternating arrangement creating a dipole-like configuration.
Each charge creates an electric field at the center of magnitude pointing radially (outward for +Q , inward for -Q ).
By vector addition of field contributions from all six charges with proper angle consideration:
The charges at specific positions create a net field with components that depend on their arrangement.

For the given symmetric configuration, the net electric field is:
This corresponds to magnitude at angle of from the positive x -axis.
