A solid homogeneous cylinder and a thin walled cylinder lie at rest in contact with one another on a rough plane inclined at $\theta\\$ to horizontal.Both cylinders have mass m and radius r.Determine the linear acc. of the cylinders if coeff. of friction is $\mu$ .how would the result change if relative positins of 2 cylinders are reversed?

by using a=(gsinx)/(1+I/(MR^2)) accn of homogenous is 2gsinx/3
and for thinwalled is g/2. So if homogenous is placed before the thin walled both move independently. For reverse get accn by writing eqns. If u can't get the answer just nudge me.

Good approach @shikhar_destructo
