Major steps for analyzing forces in uniform circular motion: Let consider one axis along the radius of circle (i.e. in direction of acceleration) and other axis perpendicular to the radius. Resolution all the forces into horizontal and vertical components.
Net force along perpendicular axis=zero
Total force along radial axis (towards centre) =mv2/r=mω2r
