A thin circular ring of radius `r` is uniformly charged over its length.Consider two points,the centre of ring `0` ,and a point `P` on the axis of the ring at a distance `a` from the centre of the ring.If ratio of potential at points `O` and `P` is `(V_(0))/(V_(p))`=`(sqrt(10))/(1)`, then value of `(a)/(r)` is ..
