7. A cylinder of mass M and radius 2R has a groove of radius R. A block Of
mass m is hung from the circumference of the cylinder and the cylinder
itself is hung from a rigid support by a thread wound on the groove as
shown in the figure.
If the acceleration of centre of mass of the cylinder is 'a1' acceleration of
the block is a2 downward and angular acceleration of the cylinder is
then relation between al, a2and will be
