thanks for your view but are my x,y,z coordinates are correct if radius R is expanding such a that R(t)=R0e^at where t is time and a,R0 are constants? Was my approach correct as i described in- The attempt at a solution

and let me correct the problem-particle confined to move on the surface of sphere whose radius is expanding such a that R(t)=R+R0e^at

yeah i expressed v and U in terms of generalized coordinates, but I'm not sure if Φ varies (i mean equation of motion for Φ)
