Question

A marble is allowed to roll down an inclined plane from a fixed
height At the foot of the-inclined plane, it moves on a horizontal
surface (a) covered with silk cloth (b) covered with a layer of
sand and (c) covered with a glass sheet On which surface, will the
marble move the longest distance

Dear Student,When the marble is rolling on the silk cloth or glass sheet, silk cloth or glass sheet will provide less frictional force to the marble as compared when marble will be rolling on the sand
Sand being rough exert more frictional force as compared to silk or glass sheet
Therefore,The marble will move the shortest distance on the layer of sand
