your concept is correct , but this can be applied if the sphere is a point object wrt ring ...
size of sphere should be very very small wrt ring ...
now see if u are multiplying field of ring with mass of sphere then at which point u are considering the whole mass???? ...
field is inversly proportional to distance of point so at different points on sphere field will be different ...
this question is based on integration ....
