1. The problem statement, all variables and given/known data
Electric charge Q is uniformly distributed around a thin ring of radius "a".Find the potential at a point p on the axis of the ring at a distance x from the centre of the ring.
2. Relevant equations
$r$=$√x^2+a^2$

3. The attempt at a solution

\

I just want to ask distributed around a thin ring of radius" a" does it mean at the distance "a" from the centre of the ring?
