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
a) |
vertically above centre of gravity |
b) |
vertically above centre of gravity |
c) |
No such point exists |
d) |
It is not possible |

The free-body diagram of the block can be drawn a shown as the body has to move in pure translation motion, the torque about the centre of gravity must be zero
