ABSTRACT 
	In this paper we have studied the effect of mean RF ponderomotive force on the 
	important tokamak tyransport candidates, which have growth rates dominated by 
	curvature, namely, ITG modes in the confinement zone , drift resistive ballooning 
	modes in the edge and curvature driven conducting wall instability in the scrape-off 
	layer.  We have also elucidated the condition under which the contribution from mean 
	ponderomotive force effects are more important than the earlier investigated Reynolds 
	stress induced velocity shear effects.
