A man of mass m stands on a plane plank of mass \(\left(\frac{\mathrm{m}}{2}\right)\), lying on a smooth horizontal floor. Initially both are at rest. Then the man starts walking on the plank towards the east and stops after a distance l on the plank. Then :
- the plank will slide to the west by a distance l/3
- the planks will continue to move towards the west over the smooth floor.
- the plank will slide to the west by \(\left(\frac{2}{3}\right)\)l and then stop
- none of the above
Answer
(C) the plank will slide to the west by ( 2 3 ) l and then stop
