As the ring is rolling without slipping,Then V=w^2*r( w- angular velocity and r- radius). Hence, inside particle will have a velocity v1=w^2*r1 and outside particle will have v2=w^2*r2We know force,F=mv^2/rNow F1/F2=(m*v1^2/r1)/ (m*v2^2/r2)Substituting the value of v1 and v2 from above, we get F1/F2= r1/r2
