“Integration is zero for a point of homogeneous body' which is that point ? 

Explain translational motion by given illustration.

$A$ uniform cylinder of mass $m$ can rotate freely about its own axis which is horizontal.$A$ particle of mass mo hangs from the end of a light string wound round the cylinder which does not slip over it. When the system is allowed to move, the acceleration of the descending mass will be

In motion of spinning top at any one place, whether the point in spinning top remains stationary or line remains stationary? 

Characteristic of rotational motion. 

Two blocks which are connected to each other by means of a massless string are placed  on two inclined planes as shown in figure. After releasing from rest, the magnitude of  acceleration of the centre of mass of both the blocks is $(g = 10\, m/s^2)$
