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?
