Field at center of uniformly charged ring is:

RankGuru · Accepted Answer

Electric field is a vector quantity.
- For a uniformly charged ring, every charge element $dq$ on one side of the ring has a corresponding charge element exactly opposite to it.
- The field vectors from these opposing pairs at the geometric center have equal magnitudes and opposite directions.
- Consequently, they cancel each other out, and the net field at the center is **Zero**.
