Please enter the following details
Steel cylinders are made so that each one has a large and small hole through the middle. In the drawing six cylinders have been stacked on top of each other. To stop the cylinders from rolling on the smooth floor they are wedged by heavy blocks at each side of bottom row. If the heavy blocks are removed what would be the position of the cylinder when they stopped rolling?
Given all the cylinders have a larger hole and a smaller hole, the centre of mass of the cylinders will be somewhere shifted towards the one with smaller hole. When left to role, the cylinder will come to rest such that the centre of mass is at the lowest possible height wrt the ground due to gravity. Only Option C shows the possible final position of the cylinders.
