Sahay Sir > Question Answers > Cengage JEE Mains Physics by B.M Sharma > Chapter 9 - Rotational Dynamics > A rectangular block of mass M and height a is resting on a smooth level surface. A force F is applied to one corner as shown in figure. At what point should a parallel force 3F 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.
