do ennergy conservation.

mgR= 1/2 I Ï‰²

I=2/5mR²

u will get omega from here.

uske baaad........ do something :P

NO need for omega..

just center of mass [1]

yes priyam u are correct :)

jus com will do...

com will shift.. so bigger sphere will move in such a way so that it compensates the movement of the com. ...
