let E be electeric field at any point P on the axis of circular ring at a distance "r " from center of axis as a cicular ring behaves as a point charge and it seems that all charge is concetrated at centre then

F =q E

where q is the charge at point on wich is experienceing force ..

F =q.K.Q/r^2

simply coulmb s law where K is constant ....
