A rectangular block of mass 
and height 
is resting on a smooth level surface. A force 
is applied to one corner as shown in Figure. At what point should a parallel force 
be applied in order that the block shall undergo pure translational motion? Assume normal contact force between the block and surface passes through the centre of gravity of the block
